Abstract:
1. A photoelectric conversion element comprising: a photoelectric conversion portion; a light path member arranged within an opening portion of an insulation film, said insulation film having an upper face extending from said opening portion, and said light path member having a lower face in a region corresponding to a light receiving face of said photoelectric conversion portion; and a light condensing member including a first layer which is a lens body layer for light condensing, a second layer positioned between said first layer and said light path member, and a third layer positioned between said second layer and said light path member, said third layer having a refractive index that is lower than said second layer; wherein said light receiving face is positioned in a first plane and said upper face is positioned in a second plane, said second plane being parallel to said first plane and being away from said first plane by a distance T; and wherein said lower face is positioned in a third plane, the third plane being parallel to said first plane and being away from said second plane toward said light receiving face side by a distance D, said distance D being equal to or smaller than said distance T; and wherein said light condensing member focuses light, which is incident upon a first area of said light condensing member corresponding to said opening portion, in a region within said light path member, and said region being between said second plane and a fourth plane, said fourth plane being parallel to said first plane and being away from said second plane toward said light receiving face side by a distance D/2.
