ABSTRACT:
There is provided a solid state image pickup device, comprising: a semiconductor substrate; a plurality of photosensitive elements formed on the surface of the semiconductor substrate; light shielding elements positioned above the substrate for covering the regions other than the photosensitive elements; a plurality of light converging elements each for converging an incident light to each of the photosensitive elements, the light converging elements being formed above the photosensitive elements at the level above the light shielding elements at a predetermined pitch; and reflecting elements formed between non-lens regions between the light converging elements and the light shielding elements, the reflecting elements each having a reflection surface for reflecting a light incident to the converging means and the non-lens regions or at least a light incident to the non-lens region toward the photosensitive element.
