Abstract
A filter for a light receiving element, which can sufficiently eliminate disturbance due to sunlight and the like out of doors. The filter for a light receiving element according to one embodiment of the present invention is used for a light receiving element which receives signal light having a known spectral distribution. The filter for a light receiving element according to one embodiment of the present invention is configured so that when the energy density of the ambient light in the light receiving element is represented by Nand the energy density of the signal light in the light receiving element is represented by N, N/(N)is minimized under constraints.
