Abstract
In a high-frequency module, a duplexer element and a matching element are mounted on a surface of a multilayer substrate. On a layer close to the surface, an individual-terminal-side wiring electrode connected to an individual terminal of the duplexer element is provided. On two layers below the layer close to the surface, first and second ground electrodes are respectively provided. On a layer below the layers on which the first and second ground electrodes are provided, a common-terminal-side wiring electrode connected to the common terminal of the duplexer element and one end of the matching element is provided. On a layer close to a bottom surface of the multilayer substrate, a third ground electrode connected to the other end of the matching element is provided.
