PROBLEM TO BE SOLVED: To provide a photo relay capable of reducing transmission loss due to parasitic capacitance between a MOSFET and an external circuit board.SOLUTION: A photo relay comprises an insulating substrate 10, input terminals 21 and 22, output terminals 31 and 32, a die pad unit 41, a light-receiving element 50, a light-emitting element 60, a MOSFET 70, and a first sealing resin layer. The insulating substrate 10 includes a first surface and a second surface. The input and output terminals each include a first conductive region. The light-receiving element 50 is bonded to the die pad 41. The light-emitting element 60 is bonded to an upper surface of the light-receiving element 50, and connected to the first conductive regions of the input terminals. The MOSFET 70 is connected to the first conductive regions of the output terminals. An extraction electrode is included in the input terminal or in the output terminal. Of the side surfaces of the insulating substrate 10, the side surface serving as an attachment surface is provided with an attachment conductive region included in the input terminal and an attachment conductive region included in the output terminal. |
