Abstract
Improvement in heat dissipation capability is intended. A radio-frequency module includes a mounting substrate, a first transmission filter, a second transmission filter, a resin layer, and a shield layer. The second transmission filter is higher in power class than the first transmission filter. The resin layer covers at least part of an outer peripheral surface of the first transmission filter and covers at least part of an outer peripheral surface of the second transmission filter. The shield layer overlaps at least part of the second transmission filter in plan view in a thickness direction of the mounting substrate. At least part of a major surface of the second transmission filter on an opposite side to the mounting substrate side is in contact with the shield layer.
