Abstract
The following configuration is adopted in order to provide a highly reliable optival sensor device which enhances the reliability of devices without making the devices unsuitable for size and thickness reductions. The light sensor comprises an element-mounting portion () having a cavity and a lid member closely attached thereinto, the lid member being composed of: a window () constituted of a phosphate-based glass to which properties approximate to a spectral luminous efficacy properties have been imparted by compositional control; and a frame () constituted of a phosphate-based glass having light-shielding properties. The lid member is a Laminated glass member obtained by cutting the phosphate-based glass having the spectral luminous efficacy properties into individual pieces, fitting the glass piece into the opening of the phosphate-based glass () 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 member.
