PROBLEM TO BE SOLVED: To efficiently condense light on a photoelectric conversion part. ! SOLUTION: A solid-state image sensor comprises: a microlens having a shape that is rotationally symmetrical with respect to the center; and a photoelectric conversion part for receiving and converting the light passing through the microlens into the electric signal, the microlens has a planar shape in which linear distances from the center to lens ends are different, and the microlens has a first bottom part near n (n is natural number) lens ends whose liner distances are relatively long, and a second bottom part not containing the first bottom part. A height Ld in vertical direction from the first bottom part to an apex of the microlens, is about 2.1 times as high as a height Lh in vertical direction from the second bottom part to the apex of the microlens. !
