The radio wave receiver includes the antenna. The device body and the closing member are coupled to each other by making the screw portion of the fixation screw being inserted through the through-hole of the metallic closing member engage with the screw portion of the device body. The coupling resin member having electrically insulating property is coupled to the irregularities of a nanometer size formed on a metal surface of the closing member, a through-hole is formed in the coupling resin member, and thereby electrical insulation between the metallic device body and the metallic closing member which are screwed together with the fixation screw is ensured so as to improve receiving sensitivity of the antenna. |
