Patent ID: 8102467

Claim:
A camera module comprising: a lens barrel in which an imaging optical system is incorporated; an image sensor that is attached to the lens barrel and picks up a subject image introduced by the imaging optical system; and a signal processing unit that performs predetermined signal processing on the pickup signal fed from the image sensor, wherein: the image sensor has an imaging surface and a back surface located opposite to the imaging surface; the image sensor is mounted with the back surface thereof directed to a flexible substrate that transmits the pickup signal; the signal processing unit is formed on a rigid printed wiring substrate; the lens barrel has a first flank and a second flank that intersect each other; the image sensor is attached to the first flank with the imaging surface thereof directed to the first flank; the flexible substrate has a projecting portion that projects from an intersectional part, at which the first flank and second flank intersect each other, with the image sensor attached to the first flank; a flexible substrate-side connector of the flexible substrate is placed on the surface of the projecting portion flush with the surface of the flexible substrate to which the image sensor is attached; a temporary lock mechanism that temporarily locks the printed wiring substrate to such an extent that the position of the printed wiring substrate can be adjusted is formed on the second flank; the printed wiring substrate is disposed on the second flank via the temporary lock mechanism; a printed wiring substrate-side connector is placed on the surface opposite to the surface of the printed wiring substrate, which faces the second flank, at a position near the intersectional part on the printed wiring substrate disposed on the second flank, and an adhesive layer is formed on the surface of the printed wiring substrate, which faces the second flank, at a position away from the printed wiring substrate-side connector; and the projecting portion of the flexible substrate is folded at the intersectional part, the flexible substrate-side connector is coupled to the printed wiring substrate-side connector, the adhesive layer is bonded to the second flank, and the flexible substrate and printed wiring substrate are thus mounted on the lens barrel.
