Abstract
An optical receiver includes a light receiving element, a carrier substrate, a dielectric layer, a base, a first conductive film, a second conductive film, a conductor, and a transimpedance. The first conductive film is provided between the light receiving element and the carrier substrate. The second conductive film is provided between the carrier substrate and the dielectric layer. A parasitic capacitance is present between the first wiring pattern of the first conductive film and the second conductive film. The conductor is electrically connected to the first wiring pattern and the second conductive film. The transimpedance has a first pad electrically connected to the first wiring pattern through a wire. An electrostatic capacitance between the second conductive film and the main surface of the base is larger than the parasitic capacitance. The inductance of the conductor is smaller than the inductance of the wire.
