Claim:
1. A switch module comprising: a multilayer substrate including a plurality of dielectric layers and a plurality of electrode layers stacked on top of one another; a switch circuit that includes a single common terminal and a plurality of switching terminals, and that is configured to be capable of switching a switching terminal to be connected to the common terminal; a common-terminal-side circuit that is connected to the common terminal and that includes a first circuit device; switching-terminal-side circuits respectively connected to the switching terminals of the switch circuit; and inner-layer ground electrodes that are respectively provided on some of the electrode layers and superposed with the switching-terminal-side circuits when viewed in plan in a stacking direction of the multilayer substrate; wherein an inner-layer ground electrode closest to the first circuit device is not superposed with the first circuit device when viewed in plan in the stacking direction of the multilayer substrate.
