It is an object of the present invention to provide a high-frequency module whose production yield as a complete module can be prevented from being lowered. The high-frequency module according to the present invention includes a main module including a first high-frequency circuit at least a part of which is constituted by a conductive pattern built in a multi-layered substrate and a sub-module including a second high-frequency circuit, and the sub-module is inserted into a cavity formed in the main module. According to the present invention, the main module including the first high-frequency circuit and the sub-module including the second high-frequency circuit are constituted as separate components and the main module and the sub-module are integrated by inserting the sub-module into the cavity formed in the main module. Therefore, it is possible to use only a main module and sub-module that have been inspected after manufacture and found to be non-defective. Accordingly, it is possible to markedly increase the yield of the high-frequency module as a whole.
