High-frequency module

A high-frequency module comprising:

• a support substrate;
• a resin base member whose one surface is fixed to the support substrate;
• a first conductive pattern formed on said one surface of the resin base member;
• a second conductive pattern formed on the other surface of the resin base member, the second conductive pattern constituting a waveguide in corporation with the first conductive pattern to pass a high-frequency signal in the resin base member and including a window for allowing entrance and exit of the high-frequency signal;
• a semiconductor element, either transmitting or receiving the high-frequency signal, mechanically and electrically connected onto the second conductive pattern at an interval from the window;
• a waveguide tube fixed onto the second conductive pattern such that one open end thereof surrounds the window;
• and
• an antenna fixed to the other open end of the waveguide tube.
