Abstract
An edge incident type light receiving element unit capable of receiving optical signals in different wavelength ranges incident from the edge side comprises a first light receiving element for receiving optical signals in a first wavelength range and a second light receiving element for receiving optical signals in a second wavelength range, and configured so that optical signals transmitted through a first light receiving portion formed vertically on a wall portion of a first semiconductor substrate incident via a reflecting portion on a second light receiving portion formed on a second semiconductor substrate fitted on the first semiconductor substrate.
