Abstract:
A member for light path to a photoelectric conversion portion includes a middle portion, and a peripheral portion having a refractive index different from the refractive index of the middle portion, and within some plane in parallel with the light receiving surface of a photoelectric conversion portion, and within other plane closer to the light receiving surface than the some plane in parallel with the light receiving surface, the peripheral portion is continuous with the middle portion and surrounds the middle portion, and also the refractive index of the peripheral portion is higher than the refractive index of an insulator film, and the thickness of the peripheral portion within the other plane is smaller than the thickness of the peripheral portion within the some plane.
