Abstract

A capsule endoscope includes a capsule type housing and a circuit board on which a plurality of board sections are arranged in a row, the circuit board being housed inside the housing in a bent state. Connection electrodes for electronic component mounting are not formed on a second principal plane of the circuit board.

Claims

1. A capsule type medical device comprising:

a capsule type housing; and

a circuit board including a first principal plane and a second principal plane, the circuit board having a plurality of board sections in a row arranged thereon, wherein

the circuit board is housed inside the housing in a bent state, and

a connection electrode for electronic component mounting is formed on the first principal plane, and the connection electrode is not formed on the second principal plane.

2. The capsule type medical device according to claim 1, wherein

the circuit board includes an opening section, and

any one of a plurality of electronic components connected to the connection electrode on the first principal plane projects from the second principal plane via the opening section of the circuit board.

3. The capsule type medical device according to claim 2, wherein the circuit board includes:

a lighting board section having a plurality of light emitting elements mounted thereon;

an image pickup board section having an image pickup chip configured to acquire image data mounted thereon;

a transmission board section having a transmission module formed by a first multilayer wiring board and configured to transmit the image data by radio mounted thereon; and

a power supply board section having a power supply module formed by a second multilayer wiring board and configured to control power supply mounted thereon.

4. The capsule type medical device according to claim 3, wherein a battery is disposed between a contact electrode of the power supply module projecting from the second principal plane and a contact electrode of the transmission module projecting from the second principal plane.

5. The capsule type medical device according to claim 4, wherein the circuit board includes:

a first lighting board section and a second lighting board section respectively arranged at both ends of the main body section and configured to light opposite directions; and

a first image pickup board section and a second image pickup board section configured to pick up images in opposite directions.
