A high-frequency module includes a mounting substrate, a filter, and a common inductor. The mounting substrate includes a first main surface and a second main surface facing each other. The filter includes series arm resonators and parallel arm resonators, and is disposed on the first main surface. The mounting substrate includes a ground terminal on the second main surface. A first end of the common inductor is connected to all of the parallel arm resonators. A second end of the common inductor is connected to the ground terminal.
