Abstract:
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 the transmission of signals between the imaging element and an imaging circuit provided outside the barrel; wherein: the imaging element comprises: the flexible circuit board comprises: 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.
