A bias circuit is provided in a circuit including an input line and an output line, and is formed on a substrate that supplies dc power to an active component. The input line reaches an input terminal of the active component from a signal line input terminal to which a signal is inputted, and the output line reaches, from an output terminal of the active component, a signal line output terminal that outputs a signal therefrom. This bias circuit includes: a power supply line supplied with the dc power; a bridge-like metal structure subjected to a bending process, which connects the output line and the power supply line to each other; and a capacitive component provided between a ground and a node between the power supply line and the metal structure.
