Provided is a low-noise amplifier that can effectively suppress noise included in an input signal. A low-noise amplifier according to an embodiment of the present invention amplifies a reception signal in a predetermined frequency band from an antenna. The low-noise amplifier includes an input terminal, an output terminal, a field effect transistor, and a branch circuit. The branch circuit is branched from a circuit connecting the input terminal or the output terminal to the field effect transistor. The branch circuit is connected to the elastic wave resonator.
