PROBLEM TO BE SOLVED: To provide a radio unit in which a directivity variable range can be broadened, design change of components can be as less as possible and installation of a lens does not require high precision when the lens is used.SOLUTION: A radio unit 1 has a first housing 2 which has a rectangular shape and a U-shaped cross-section, a radio unit board 5 which is mounted in a first housing 2 and has an antenna element 3 operating in a milli-wave zone at a part of a face confronting the opening side of the first housing 2 and in which a radio module 4 is mounted, and a second housing 6 which is configured in a rectangular shape so as to be securable at the opening side of the first housing 2, and has an opening portion 6a at the position corresponding to an antenna element 3 of the radio module 4. |
