ABSTRACT:
Disclosed is light-receiving device (1) comprising semiconductor substrate (101), a light-receiving layer arranged on semiconductor substrate (101), and filter layer (103) arranged between semiconductor substrate (101) and the light-receiving layer to absorb light other than reception light. First mesa (11) serving as the light-receiving layer is surrounded by third mesa (13) for absorbing at least light other than reception light. Consequently, even when filter layer (103) is too thin to sufficiently absorb light other than reception light, third mesa (13) absorbs the light, thereby preventing the light from reaching first mesa (11).
