Patent ID: 8106952

Claim:
An imaging device unit comprising: an imaging device having an imaging surface located on one side thereof in a width direction thereof and a rear surface located oppositely to the imaging surface; a heat radiating plate radiating heat generated in the imaging device, the heat radiating plate being arranged at the rear surface of the imaging device; and a signal processing substrate causing the imaging device to be operated, wherein the heat radiating plate and the signal processing substrate are arranged opposedly to each other with a spacer being interposed therebetween and with a space portion being obtained therebetween, the heat radiating plate has a contour larger than the imaging device, the imaging device is arranged so as to be located in the contour of the heat radiating plate, as viewed from a width direction of the heat radiating plate, the imaging device has a plurality of leads transmitting electrical power and a drive signal, which are supplied to the imaging device, and a picked-up imaging signal generated in the imaging device, the plurality of leads projecting from a periphery of the imaging device, and the heat radiating plate has elongated holes formed in regions thereof which are adjacent edge portions of the heat radiating plate, the elongated holes being formed so as to extend along the edge portions of the heat radiating plate, and the signal processing substrate has connections portions, the leads being inserted through the elongated holes and connected at end portions thereof to the connection portions by soldering.
