A solid-state imaging device is provided. The solid-state imaging device includes a plurality of arrayed pixels, an optical inner filter layer, and a light-blocking side wall. The plurality of arrayed pixels each includes a photoelectric conversion portion and a pixel transistor. The optical inner filter layer is provided for blocking infrared light and formed facing toward a light-receiving surface of the photoelectric conversion portion of a desired pixel among the arrayed pixels. The light-blocking side wall is formed on a lateral wall of the optical inner filter layer.
