In order to provide a highly reliable light sensor which enhances the reliability of devices without making the devices unsuitable for size and thickness reductions, the following configuration is adopted. The light sensor comprises an element mounting part (3) having a cavity and a cover tightly bonded and fitted thereinto, the cover being composed of: a window (2) constituted of a phosphate-based glass to which properties approximate to luminosity characteristics have been imparted by compositional control; and a frame (1) constituted of a phosphate-based glass having light-shielding properties. The cover is a bonded glass object obtained by cutting the phosphate-based glass having luminosity characteristics into a piece, fitting the glass piece into the opening of the phosphate-based glass (1) having light-shielding properties, the opening having been formed so as to have a size approximately equal to the cavity size, and melting and integrating the glasses.
