Abstract
An image sensing element having a high refractive index part that covers at least a portion of each of a plurality of photoelectric converters arranged in one or two dimensions and a low refractive index part provided on the periphery of the high refractive index part. The interface between the high refractive index part and the low refractive index part has a surface that is substantially parallel to the optical axis of an image sensing lens and a slanted surface having an angle that differs from that of the parallel surface. The slanted surface is disposed on a portion of a surface near the optical axis of the image sensing lens, the portion being on a side that light rays from the image sensing lens enters the image sensing element.
