Patent ID: 8153951

Claim:
An optical communication device, comprising: a one-chip light receiving element having a plurality of light receiving sections with light receiving sensitivity to different wavelength ranges in a visible light spectrum, wherein the plurality of light receiving sections are divided into different light receiving section groups by the wavelength range to which the light receiving sections have the light receiving sensitivity, each light receiving section group including a plurality of light receiving sections, the light receiving element has a light receiving surface divided into a plurality of blocks arranged in rows and columns, the light receiving sections constituting one light receiving section group having the light receiving sensitivity to an identical wavelength range are dispersedly placed over the light receiving surface, with these light receiving sections being placed in the respective blocks of the light receiving surface that are not adjacent to each other in a row direction nor in a column direction, and the light receiving sections in one light receiving section group having the light receiving sensitivity to an identical wavelength range are connected to each other via joints.
