Abstract

The present invention relates to: a solid-state imaging element which is capable of providing a solid-state imaging element that comprises a polarizing element which has simple configuration and structure based on wire grid polarizer technology; a solid-state imaging device; an imaging apparatus; and a method for producing a polarizing element. The solid-state imaging device comprises a plurality of solid-state imaging elements (41) each of which comprises a photoelectric conversion element (61) and a polarizing element (70) that is arranged on the light incident side of the photoelectric conversion element (61). The solid-state imaging device comprises two or more kinds of polarizing elements (70) that have different polarization directions, and each polarizing element has a lamination structure wherein a stripe-patterned reflective layer (71), an insulating layer (72) that is formed on the reflective layer (71) and a light absorption layer (73), which is composed of a plurality of pieces (73') that are formed on the insulating layer (72) so as to be separated from each other, are laminated from the photoelectric conversion element side.
