Abstract
A radio-frequency module includes a mount board, an acoustic wave filter, a metal block, a resin layer, and a shield layer. The mount board has a first principal surface and a second principal surface opposite to each other, and has a ground layer. The acoustic wave filter is mounted on the first principal surface of the mount board. The metal block is disposed on the first principal surface of the mount board, and is connected to the ground layer. The resin layer is disposed on the first principal surface of the mount board, and covers the periphery of the acoustic wave filter and the periphery of the metal block. The shield layer covers the principal surface, which is on the opposite side to the mount board side, of the acoustic wave filter, the resin layer, and the metal block. The metal block is in contact with the shield layer.
