Abstract
A solid-state imaging device Comprising a photosensing portion for performing opto-electric conversion and a light shielding film formed so as not to cover a photosensing surface of the photosensing portion. An overcoat layer formed of a first transparent material is formed so as to cover the photosensing surface of the photosensing portion, and a recessed portion is formed in the overcoat layer at a position just above the photosensing surface. The recessed portion has a top surface having a concavity toward the photosensing surface. A lens portion formed of a second transparent material having a refractive index higher than that of the first transparent material is embedded in the recessed portion.
