Abstract:
1. An image sensor module comprising: a lens member including a first surface and a second surface opposite to the first surface; a frame that holds the lens member, the frame including a loop-shaped top surface and a base surface opposite to the top surface, the frame being internally provided with a lens holding space for accommodating the lens member in a manner such that the lens member avoids protruding beyond the top surface of the frame; a diaphragm formed on the first surface of the lens member, the diaphragm including an opening and a light-shielding portion; an image sensor chip that receives light converged by the lens member; and a board upon which the image sensor chip is mounted, the board being fixed to the base surface of the frame; wherein the first surface of the lens member includes a flat torus portion and a concave portion surrounded by the torus portion, the concave portion corresponding in position to the opening of the diaphragm, the concave portion projecting toward the second surface of the lens member from the torus portion, wherein the diaphragm is made of light-shielding ink, the light-shielding portion of the diaphragm being entirely held in direct contact with the flat torus portion of the lens member, the diaphragm being substantially flush with the top surface of the frame.
