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. ## Claims ### Claim 1 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;
