Image quality degradation due to external light irradiated to an edge section of a transparent cover of a solid-state imaging device and external light propagating in the cover is prevented with a simple structure. A glass cover 60 formed to cover the whole surface of an imaging region 26 of a solid-state imaging element 10 is constituted by a transmission section 60a corresponding to the imaging region 26, and an edge section 60b that surrounds the transmission section 60a outside the transmission section 60a. The edge section 60b of the cover 60 is selectively removed around a periphery of the edge section 60b, thereby forming a frustum-shaped part whose cross-sectional area decreases monotonously from its exit side to its incidence side in the cover 60. An optical function film 63 having an optical absorption, reflection, or scattering action is formed on an outer face of the frustum-shaped part. |
