PURPOSE:To improve sensitivity, especially FM sensitivity, and to simplify the constitution of an antenna without the influence of a defogger heating coil by arranging an antenna line on a window glass in a crossing direction with the defogger heating wire so as to be insulated from the heating wire. CONSTITUTION:A rear window glass 1 is a laminated glass obtained by superposing two glasses 1a, 1b and the defogger heating wire 3 is printed on the surface of the glass 1b arranged on the room side. The antenna line 9 is arranged on the joined part of the glasses 1a, 1b, a feeder terminal 11 is arranged on the upper part of the glass 1b on the room side and both the line 9 and terminal 11 are connected through a thin hole 13. To prevent the joined part of the glasses from the generation of a gap, a notched groove corresponding to the thickness of the antenna line 9 is formed on any one of the glasses 1a, 1b, the line 9 is set up on the groove and then the glasses 1a, 1b are superposed. |
