Abstract
A camera module (1) is an assembly of a lens holder (4) and a wiring board (2). The lens holder (4) holds an optical structure (3) which forms an image of a subject. The wiring board (2) has formed thereon a solid-state image sensing element (21) which converts the image of the subject formed by the optical structure (3) to electrical signals. Grease (7) is applied to the camera module (1) in such a manner that the grease is not present in an optical path in the optical structure (3). The grease (7) catches the dust (D) produced during manufacture and while in use, thereby prevented the dust (D) from causing image defects. A solid-state image sensing device is thus provided which is capable of preventing the dust produced during manufacture and while in use from causing image defects.
