Abstract:
A radio-frequency module includes: a module substrate having a major face; a first circuit component and a second circuit component that are disposed over the major face; a resin component that covers the first circuit component and the second circuit component; a metal shield layer that covers a surface of the resin component; a metal shield plate that is disposed over the major face and, with the module substrate seen in plan view, located between the first circuit component and the second circuit component; and a via-conductor disposed in the module substrate and set to a ground potential. The metal shield plate is in contact with the metal shield layer, and connected at the major face with the via-conductor. The metal shield plate has a thickness greater than a thickness of the metal shield layer and less than or equal to an outside diameter (of the via-conductor.
