A solid-state imaging device according to the present invention includes pixels which are arranged two-dimensionally and each of which includes: a light absorbing layer that converts light into signal charges; a signal read circuit to read out the signal charges, the signal read circuit being formed on a side opposite to a light incident plane side of the light absorbing layer; a metal layer that is formed on the light incident plane side of the light absorbing layer, the metal layer having an aperture to transmit, into the light absorbing layer, light of a wavelength range depending on a shape of the aperture, a driving circuit that applies a voltage to the metal layer to generate, in the light absorbing layer, a potential gradient to collect the signal charges.
