An RF module includes a switch IC on a surface of a module substrate and a passive circuit provided in and/or on the module substrate. The switch IC includes a high-frequency circuit on an IC substrate and a digital control circuit. In a plan view of the IC substrate, the digital control circuit is surrounded by the high-frequency circuit. The high-frequency circuit includes analog ground electrodes in a boundary portion with the digital control circuit in the high-frequency circuit to surround the digital control circuit in the plan view.
