PROBLEM TO BE SOLVED: To provide a camera device allowing a longer cam than traditional cam structures, increasing the resolution of focus position adjustment. SOLUTION: The camera device 1 includes: a support frame 8 that supports an imaging element 6; a focus position adjustment frame 9 having a cylindrical part 18 into which the support frame 8 is inserted so as to be slidable; and a focus position adjustment ring 10 having a ring-shaped main part 24 that is fitted around the cylindrical part 18. The outside surface of the cylindrical part 18 includes a screw-shaped cam part 23, and the inside surface of the main part 24 includes a screw part 25 having a shape corresponding to the cam part 23. The focus position adjustment ring 10 is rotated and thereby moved in the direction of the optical axis. The support frame 8 includes: spring-attachment prongs 15 which abut against the focus position adjustment ring 10; and coil springs 16 which push the support frame 8 toward the focus position adjustment ring 10.
