Abstract
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 coverformed to cover the whole surface of an imaging regionof a solid-state imaging elementis constituted by a transmission sectioncorresponding to the imaging region, and an edge sectionthat surrounds the transmission sectionoutside the transmission section. The edge sectionof the coveris selectively removed around a periphery of the edge section, thereby forming a frustum-shaped part whose cross-sectional area decreases monotonously from its exit side to its incidence side in the cover. An optical function filmhaving an optical absorption, reflection, or scattering action is formed on an outer face of the frustum-shaped part.
