PROBLEM TO BE SOLVED: To provide a photocoupler having excellent noise resistance.SOLUTION: A photocoupler 100 includes a light emitting part 101 and a light receiving part 102. The light emitting part 101 outputs an optical signal L1 in accordance with an input electric signal. The light receiving part 102 includes a high-sensitivity PD 21 and a low-sensitivity PD 22. The light receiving part 102 is electrically insulated from the light emitting part 101 and outputs an electric signal converted from the optical signal L1. The cathode of the high-sensitivity PD 21 and the anode of the low-sensitivity PD 22 are connected to an output terminal OUT. |
