Lens barrel and imaging apparatus
First Claim
1. A lens barrel comprising:
- an optical system provided inside a barrel for guiding a subject image;
an imaging element provided on an optical path of the optical system inside the barrel; and
a flexible circuit board connected to the imaging element for performing transmission of signals between the imaging element and an imaging circuit provided outside the barrel;
wherein;
the imaging element comprises;
a package having a plate-like shape;
an imaging unit housed in the package so as to face an obverse face of the package; and
a plurality of first connecting terminals provided on a rear face of the package;
the flexible circuit board comprises;
an imaging-element mounting section;
an extending section extended from the imaging-element mounting section; and
a connecting section provided in an end of the extending section and connected to the imaging circuit;
the imaging-element mounting section comprises a plurality of second connecting terminals provided on a surface of the flexible circuit board so as to correspond to respective first connecting terminals;
the package is mounted on the imaging-element mounting section with the first connecting terminals respectively connected to the second connecting terminals by soldering;
a metal plate capable of retaining its rigidity at a heating temperature by which each of the first connecting terminals and the corresponding second connecting terminal is soldered is provided which, as viewed from a thicknesswise direction of the package, has an outline which is approximately the same as the package, or an outline which is larger than that of the package so that the outline of the package is contained in that of the metal plate; and
the metal plate is mounted at a position where the outline of the metal plate matches the outline of the package or the outline of the package is placed in the outline of the metal plate as viewed from the thicknesswise direction of the package, on the rear face of the imaging-element mounting section.

Abstract
To provide a lens barrel and an imaging apparatus for securely connecting imaging element with imaging circuit and advantageous in terms of downsizing of devices. A plurality of first connecting terminals is provided to a bottom face of an imaging element package. A flexible circuit board is constituted by an imaging element mounting section, an extending section and a connecting section. The imaging element mounting section includes a flexible circuit board and a plurality of second connecting terminals provided on a surface of the flexible circuit board so that each of the second connecting terminals match with a corresponding first connecting terminal. A metal plate is mounted at a position where the outline of the metal plate matches the outline of the package or the outline of the package is placed in the outline of the metal plate as viewed from the thicknesswise direction of the package, on the rear face of the imaging-element mounting section.
