Abstract:
A radio-frequency module includes: plural electronic components that include plural bare SAW devices and that are disposed between a major surface of a module substrate and a major surface of a module substrate, on a major surface of the module substrate, and on a major surface of the module substrate; plural external connection terminals disposed on the major surface; and resin members. The resin member covers the plural SAW devices but does not fill between central regions of the plural bare SAW devices in which the IDT electrodes are disposed and the major surface to which plural bump electrodes are joined. The plural bare SAW devices are disposed on the major surface, and no bare SAW devices are disposed between the major surfaces and on the major surface.
