Optical detection device, optical device, optical information reading device, and light source fixing method

Abstract

Provided is an optical detecting device, wherein a photodiode is provided on a first surface of a substrate, a planar output electrode for outputting electrical signals corresponding to a quantity of light received by the photodiode is provided on a second surface of the substrate opposite to the first surface, a cutout portion is provided in a third surface of the substrate such that the cutout portion is in contact with the output electrode provided on the second surface, said third surface being different from the first surface and the second surface, and an electrode connected to the output electrode is provided on the inner surface of the cutout portion.

Dependencies are inferred from the claim text.
