In a solid-state image pickup device, it is difficult to match an optimum incidence angle corresponding to an image height of a pixel array region with light incidence characteristics of a camera lens, thereby causing image quality deterioration due to sensitivity shading. Respective microlenses are disposed in a two-dimensional manner, i.e., in a row and a column directions. In particular, the microlenses are disposed such that each side of a disposition region where the microlenses are disposed has a concave curve with respect to a line connecting adjacent vertexes of the disposition region. In other words, a distance AH (AV) between center points of a pair of facing sides of the disposition region is set to be smaller than a distance BH (BV) between neighboring vertexes of the disposition region.
