Abstract

PURPOSE:To provide a light receiving device, in which a light receiving element is irradiated with an outside light to prevent the bias light from leaking to the outside, by arranging such a filter in front of the light receiving element as is used to compensate the spectroscopic sensitivity of a preset wavelength range.
