ABSTRACT:
A solid-state image sensing device includes an image sensing element and a light transmissive plate provided over the element. The plate contains borosilicate glass and the dose of radioactive .beta. rays emitted therefrom is small. The plate further contains potassium-based oxide the content of which is 0.1 or less in Wt %. The plate is provided with, at least, one non-reflective film attached to a surface thereof, the surface facing a light-receiving surface of the element. By means of the film, the .beta. rays emitted from the plate further becomes small.
