Abstract

Provided is a photodetection apparatus which includes a mounting board, and an optical sensor device that includes a first surface on the mounting board side and a second surface on a side opposite to the mounting board, and is mounted on the mounting board. The optical sensor device includes an optical sensor that includes a light receiving surface on the second surface side, a signal processing circuit that is electrically connected to the optical sensor, and a lead frame that is provided on the second surface side with respect to the signal processing circuit, and shields a surface of the signal processing circuit on the second surface side. The mounting board has a conductive pattern that faces the signal processing circuit and shields a surface of the signal processing circuit on the first surface side.
