Abstract
Provided is a high-reliability, compact, and low-cost optical sensor device. The optical sensor device includes a glass lid substrate (), a glass substrate () with a cavity having divided and exposed through-hole electrodes () on the periphery thereof, and an optical sensor element () mounted on the glass lid substrate, and has a structure in which the glass lid substrate and the glass substrate with a cavity are bonded together. By hermetically sealing with the glass substrates, high reliability is secured. By using the divided through-hole electrodes, the package size is reduced and the number of devices which can be produced in a batch in the manufacture increases, which enables cost reduction.
