Imaging device

An imaging device comprising:

• a lens barrel for holding a lens;
• an element holder adhesively secured to one end of the lens barrel in an optical axis direction of the lens while holding an imaging element;
• and
• an elastic body disposed between the lens barrel and the element holder in the optical axis direction, wherein
• one of the lens barrel and the element holder has formed thereon a projection projecting in the optical axis direction toward the other of the lens barrel and the element holder,
• the other of the lens barrel and the element holder has formed therein an insertion hole into which the projection is inserted,
• the elastic body has formed therein a through hole through which the projection is inserted,
• the elastic body is fitted to the projection with the projection inserted in the through hole,
• an outer peripheral surface of the projection and an inner peripheral surface of the through hole are in contact with each other,
• the other of the lens barrel and the element holder in which the insertion hole is formed and the elastic body fitted to the projection are in contact with each other on a periphery of the insertion hole, and
• an adhesive for fixing the lens barrel and the element holder is filled between the outer peripheral surface of the projection and the inner peripheral surface of the insertion hole.
