An optical communication device includes a one-chip light receiving element having a plurality of light receiving sections having light receiving sensitivity to different wavelength ranges in a visible light spectrum. The photodiode has a light receiving surface, which is divided into nine blocks. For each light receiving section group in which light receiving sections have the light receiving sensitivity to an identical wavelength range, the light receiving sections are dispersedly placed in corresponding ones of the blocks.
