Abstract
A sensor portion of an integrated photo sensor is composed of a silicon substrate, a photo diode and a signal processing element which are provided on the silicon substrate separately from each other. A shading film is provided on a surface region of the substrate except a region above the photo diode, and an intermediate insulating film made of silicon oxide is provided between the silicon substrate and the shading film. The intermediate insulating film includes a part extending on a light-receiving region of the photo diode, and the part is covered with light transmittable gel having a refractive index approximately equal to that of the intermediate insulating film.
