To provide a method for producing a solid-state imaging device enabling an improvement of a light sensitivity characteristic in a light receiving unit, a solid-state imaging device in which the light sensitivity characteristic is improved, and a camera provided with the solid-state imaging device. A shield film projected around the light receiving unit is formed on a substrate in which the light receiving unit is formed; an transparent insulation film is formed on the shield film; a sidewall insulation film is formed by etch-back of the insulation film, in a side wall of the shield film; a mask layer having an aperture at a position corresponding to the light receiving unit is formed on the shield film; and the shield film is etched by using the sidewall insulation film and the mask layer as a mask to form an aperture portion exposing the light receiving unit.
