Abstract

A solid-state image pickup device, comprising:

• • a solid-state image pickup element;
  • a circuit-board main body to which the solid-state image pickup element is connected;
  • a shield piece consecutively connected to the circuit-board main body, capable of being folded, and having a shield pattern disposed; and
  • a signal cable which is connected to a connection terminal disposed on the circuit-board main body and transmits an input/output signal to the solid-state image pickup element, wherein
  • the shield piece is folded at least to one face side of a region where the connection terminal is formed.

Claims

1. A solid-state image pickup device, comprising:

a solid-state image pickup element;

a circuit-board main body to which the solid-state image pickup element is connected;

a shield piece consecutively connected to the circuit-board main body, capable of being folded, and having a shield pattern disposed; and

a signal cable which is connected to a connection terminal disposed on the circuit-board main body and transmits an input/output signal to the solid-state image pickup element, wherein

the shield piece is folded at least to one face side of a region where the connection terminal is formed.

2. The solid-state image pickup device according to claim 1, wherein

if the connection terminal is projected onto the same plane as the shield pattern disposed on the shield piece, the connection terminal is contained within the shield pattern.

3. The solid-state image pickup device according to claim 1, wherein

the shield piece is folded so as to become substantially in parallel with the circuit-board main body.

4. The solid-state image pickup device according to claim 1, wherein

at least two shield pieces are consecutively connected to the circuit-board main body, capable of being folded;

and

the two shield pieces are folded so as to overlap each other.

5. The solid-state image pickup device according to claim 1, wherein

a shield layer is disposed on the signal cable side;

an opening portion from which the shield pattern is exposed is formed in the shield piece; and

the shield piece is folded so that the shield pattern exposed from the opening portion is in contact with the shield layer.

6. The solid-state image pickup device according to claim 1, further comprising:

a consecutive connecting portion that consecutively connects the circuit-board main body to the shield piece, where

the shield pattern is extended to at least a part of the consecutive connecting portion.

7. The solid-state image pickup device according to claim 1, wherein

the circuit-board main body and the shield piece are formed integrally from a flexible board having flexibility.

8. The solid-state image pickup device according to claim 1, wherein

peripheral portions of the shield piece and the connection terminal are sealed and fixed by a resin.

9. An endoscopic device including the solid-state image pickup device according to claim 1 at a distal end of an insertion portion to be inserted into a subject body.

10. The endoscopic device according to claim 9, further comprising:

a forceps channel communicating with a forceps outlet formed in the distal end of the insertion portion and through which a treatment instrument that performs a procedure on the subject body is inserted, wherein

the shield piece is folded so as to be arranged between the connection terminal and the forceps channel.
