HIGH-FREQUENCY MODULE AND COMMUNICATION DEVICE

WIPO Patent Application WO/2022/270330

A1

In the present invention, deterioration in characteristics of a filter is reduced. In a high-frequency module (500), a filter includes: a first substrate; a first function electrode (11) that is provided on the first substrate and that constitutes a part of an antenna terminal resonator (14A); a second substrate separated from the first substrate; and a second function electrode that is provided on the second substrate and that constitutes a part of at least one elastic wave resonator other than the antenna terminal resonator (14A) among a plurality of elastic wave resonators. A first electronic component (E1) including the first substrate and the first function electrode (11) is disposed on the first main surface (111) of a mounting substrate (110). An inductor (4) is adjacent to the first electronic component (E1) in a plan view from the thickness direction of the mounting substrate (110). The inductor (4) does not overlap the antenna terminal resonator (14A) in a side view from the direction of a winding shaft (A4) of a winding portion.
