Beschreibung
Zusammenfassung:	A light detection device includes an APD, a plurality of temperature compensation diodes, and a circuit unit. The plurality of temperature compensation diodes have different breakdown voltages lower than a breakdown voltage of the APD. The circuit unit puts any one of the plurality of temperature compensation diodes into a breakdown state. The circuit unit includes a plurality of terminals and a terminal. The plurality of terminals are respectively connected to electrodes of the mutually different temperature compensation diodes. The terminal is electrically connected to the APD and electrodes of the temperature compensation diodes.
