<p>A member for light path (220) to a photoelectric conversion portion (110) includes a middle portion (222), and a peripheral portion (221) having a refractive index different from the refractive index of the middle portion (222), and within some plane in parallel with the light receiving surface (111) of the photoelectric conversion portion (110), and within other plane closer to the light receiving surface (111) than the some plane in parallel with the light receiving surface (111), the peripheral portion (221) is continuous with the middle portion (222) and surrounds the middle portion (222), and also the refractive index of the peripheral portion (221) is higher than the refractive index of an insulator film (200), and the thickness (TH4) of the peripheral portion (221) within the other plane is smaller than the thickness (TH2) of the peripheral portion (221) within the some plane.</p> |
