An LNB converter includes a first frame made of metal and having an edge, and a second frame made of metal and having an opposite portion opposed to the edge. It also includes a dielectric substrate arranged in a space surrounded by the first frame and second frame. The dielectric substrate includes a conductor pattern formed at a surface of the dielectric substrate. The edge and the opposite portion are fixed together by a seal member. A cushion member is arranged between the edge and the opposite portion. The cushion member is arranged to prevent the seal member from entering the space surrounded by the first frame and second frame and coming into contact with the dielectric substrate.
