A rear window glass sheet 10 includes a plurality of heating wires 2 and a plurality of bus bars 5 a and 5 b for feeding the heating wires 2 , the heating wires 2 and the bus bars form a defogger, the heating wires 2 extend in a horizontal direction of the rear window glass sheet 10 , and an antenna conductor 6 is disposed in an upper blank region of the rear window glass sheet 10 except for a defogger region. When it is assumed that there is a line, which passes through the center of the antenna conductor 6 in a left-to-right direction of the antenna conductor or the center of gravity thereof, and which extends parallel to the heating wire at the highest position, is called an imaginary parallel line 11 , an island-like conductor 1 a is disposed in an region of the rear window glass sheet 10 between the imaginary parallel line 11 and the heating wire 2 a at the highest position as viewed three-dimensionally.
