Abstract
The present technology relates to a solid-state imaging device, an imaging apparatus, and an electronic apparatus, which can suppress a color mixture without lowering the sensitivity. In pixels (red pixels (R pixels), green pixels (G pixels), and blue pixels (B pixels)) other than W pixels and adjacent to the W pixels, light shielding films thicker than those of the W pixels are formed at positions adjacent to the W pixels. Furthermore, the shorter the wavelength, the thicker the light shielding film in the RGB pixels other than the W pixels. The present technology is applicable to the solid-state imaging device.

A solid-state imaging device, comprising:
- a filter configured to extract and pass, pixel-by-pixel, white light that is incident light itself and light of a plurality of specific wavelengths;
- and
- an inter-pixel light shielding film configured to shield, pixel-by-pixel, light from an adjacent pixel in the filter,
- wherein the inter-pixel light shielding film in a pixel that passes the white light is thinner, in a region adjacent to a pixel that passes light of another specific wavelength, than the inter-pixel light shielding film in the pixel that passes light of another specific wavelength.
