An array type light-receiving device includes a plurality of pixels two-dimensionally arranged in a first direction and a second direction perpendicular to the first direction, each of the pixels including a light-receiving layer having a responsivity to a wavelength of light. The pixels arranged in the second direction constitute a plurality of pixel lines extending in the second direction, the plurality of pixel lines being arranged in the first direction to form an array. The pixels in each of the pixel lines have different pixel areas from each other. In addition, the pixel area of each of the pixels included in at least one of the pixel lines is determined in accordance with the responsivity to a wavelength of light received by each of the pixels.
