A solid-state imaging device comprises: a solid-state imaging element comprising a solid-state imaging element body; a first substrate one end face of which is bonded to and integrated with one end face of a solid-state imaging element substrate of the solid-state imaging element, the first substrate comprising on its one surface an electrode for establishing electrical contact with a bonding wire led from a pad provided on one surface of the solid-state imaging element, a frame that seals the solid-state imaging element so as to surround outer peripheral surfaces of the solid-state imaging element substrate excluding its the one end face; and a sealing resin portion that covers a region extending from a portion including the electrode on the one surface of the first substrate to a portion including the pad on the one surface of the solid-state imaging element.
