A camera module 1 includes: an optical structure 3 that forms a subject image and moves up and down along an optical path; a solid-state image pickup element 21 that converts, into an electrical signal, a subject image formed by the optical structure 3; a lens holder 4, holding the optical structure 3 therein, which contains the solid-state image pickup element 21, the optical structure 3 having a cushioning member 34 so provided on a back surface thereof as to absorb the impact of contact between the optical structure 3 and the holding section 4. The cushioning member 34 has a removing section for, when in contact with a contact surface 4a of the holding section 4, removing dust D on the contact surface 4a outward from the contact surface 4a. This makes it possible to provide a small camera module 1 while preventing (reducing) dust from causing an image defect.
