Color light receiving device and image pickup device

An image pickup device in which a plurality of light receiving devices are arranged, wherein the light receiving device comprise a semiconductor substrate and a short-wavelength light receiving section provided on or above a surface of a light entering side of the semiconductor substrate, wherein:

• the semiconductor substrate comprises regions of a first conductivity type and regions of a second conductivity type in an altemately multiply laminated manner, wherein the second conductivity type is a conductivity type opposite to the first conductivity type;
• each of junction surfaces between the regions of the first conductivity type and the regions of the second conductivity type is formed to have a depth which enables converting light in a wavelength band, which is different from light in other wavelength band(s) converted by other junction surfaces, to electricity;
• and
• the shortwavelength light receiving section is separated from the semiconductor device by at least an insulating layer and detects light having a wavelength shorter than the central wavelength(s) of all the respective wavelength band(s) converted by the junction surfaces.
