Abstract

Provided is a semiconductor device including: a multilayer substrate including an optical element; a light-transmitting plate provided on the substrate to cover the optical element; and a lens of an inorganic material provided between the substrate and the light-transmitting plate. A structure having a same strength as a strength per unit area of the lens is provided at a portion outside an effective photosensitive region where the optical element is formed, when the substrate is viewed in plan.
