A first filter is prevented from being affected by the coplanarity of a mounting substrate and a degradation of the filter characteristics of the first filter is reduced. A first filter, a second filter, a third filter, and a first switch are mounted on a first principal surface of a mounting substrate. The first filter passes a first high-frequency signal and a second high-frequency signal, the second filter passes a third high-frequency signal, and the third filter passes a fourth high-frequency signal. The first switch is capable of simultaneously connecting the first filter and the second filter to an antenna terminal. In a plan view from a thickness direction of the mounting substrate, the first filter is larger than the second filter and the third filter and located between the second filter and the third filter. A first wire and a second wire are each shorter than a third wire.
