PROBLEM TO BE SOLVED: To provide a high frequency glass antenna for an automobile which improves antenna gain of antenna conductors disposed above a defogger. SOLUTION: A rear window glass sheet 10 comprises a plurality of heating wires and a plurality of bus bars 5a, 5b, 5c, 5d for feeding the plurality of heating wires and antenna conductors 6, 7 are disposed in the upper margin of the rear window glass sheet 10 other than a defogger region. A straight line is assumed which is parallel with a surface in parallel with the lengthwise direction and the perpendicular direction of an automobile, passes through the center or the center of gravity of the antenna conductors 6, 7 and passes through at least one of the plurality of heating wires. When such a straight line is called virtual straight line, at a position where the virtual straight line crosses or crosses in a three-dimensional manner a highest heating wire, an interval between the highest heating wire and a heating wire just under the highest heating wire is made into 42 mm or more.
