PROBLEM TO BE SOLVED: To provide a device which can be accurately mounted on an automobile rear window or the like so that required antenna characteristics can be always stably developed by providing an driven antenna arranged so as to be made adjacent to a defogger, and so as to be faced to the defogger with a prescribed clearance so that one side can be mutually closely connected with one side of the defogger. SOLUTION: A non-loop type driven antenna 20 in a configuration that a part of a rectangular loop is cut is arranged in a longitudinal region on a window glass 101 which is present between the uppermost part of a defogger 10 and window frame upper edge part. The driven antenna 20 is formed of strip- shaped conductors whose thickness is thin and whose width is narrow in the same way as the defogger 10. The driven antenna 20 is arranged so as to be made adjacent to the defogger 10, and so as to be faced to the defogger 10 with a prescribed clearance so that one side of the driven antenna 20, that is, a bottom side 20a can be mutually closely connected with one side of the defogger 10, that is, a wire 10a at the uppermost part among plural horizontal wires 10a.
