Abstract: Each imaging pixel provided in a solid-state imaging device includes a charge accumulation part which is a diffusion region formed in a substrate, a gate electrode formed lateral to the charge accumulation part on the substrate, an insulating film formed on the charge accumulation part, and a contact plug connected to the charge accumulation part so as to penetrate the insulating film and made of semiconductor. The contact plug is, at a lower part thereof, embedded in the insulating film, and is, at an upper part thereof, exposed through the insulating film. Silicide is formed on the upper part of the contact plug, and the charge accumulation part and the gate electrode are covered by the insulating film.
