Abstract:
A radio frequency module includes a wiring substrate, a plurality of components mounted on an upper surface of the wiring substrate, a sealing resin layer laminated on the upper surface of the wiring substrate and covering the plurality of components, a groove formed in an upper surface of the sealing resin layer and extending between predetermined components of the plurality of components, and a shielding wall made of conductive paste in the groove. The sealing resin layer has a stepped area defining the higher portion and lower portion in the upper surface. The groove intersects the stepped area when the wiring substrate is seen in plan view.
