Abstract
A camera module includes a solid-state image sensing device having a light receiving surface on which a plurality of pixels are provided, and a lens disposed above the solid-state image sensing device and configured to direct light into each of the pixels of the solid-state image sensing device. The lens includes at least one convex portion on a surface facing the light receiving surface of the solid-state image sensing device, and the light receiving surface of the solid-state image sensing device is curved so that chief rays of the light directed by the lens are incident on the respective pixels at substantially the same angles.
