摘要： A solid-state imaging apparatus includes a plurality of unit pixels with associated microlenses arranged in a two-dimensional array. Each microlens includes a distributed index lens with a modulated effective refractive index distribution obtained by including a combination of a plurality of patterns having a concentric structure, the plurality of patterns being divided into line widths equal to or shorter than a wavelength of an incident light. At least one of the plurality of patterns includes a lower light-transmitting film having the concentric structure and a first line width and a first film thickness, and an upper light-transmitting film having the concentric structure configured on the lower light-transmitting film having a second line width and a second film thickness. The distributed index lens has a structure in which a refractive index material is dense at a center and becomes sparse gradually toward an outer side in the concentric structure.
