ABSTRACT:
A semiconductor light receiving device includes a plurality of photodiode units, each of which is configured to convert a received light into an electric signal; and a separating unit configured to electrically separates the plurality of photodiode units from each other. The impurity concentration of a surface portion of the separating unit is equal to or lower than a first concentration. The first concentration is a concentration at which the light receiving sensitivity of the separating unit to light is substantially equal to the light receiving sensitivity of each of the plurality of photodiode units of the light. A wavelength of the light is equal to or longer than that of blue-violet light.
