PROBLEM TO BE SOLVED: To provide a glass antenna for vehicle or the like in which both glass antennas can coexist by suppressing deterioration in the antenna gain of both glass antennas even though the antenna conductor of a glass antenna of another medium is electrically connected to a defogger to which a ground side feeding part of a two-pole type glass antenna is electrically connected. SOLUTION: In the glass antenna for vehicle in which an antenna conductor 22 for a first frequency band, an antenna conductor 21 for a second frequency band having a higher frequency than that of the first frequency band, and a feeding part 16 and a ground side feeding part 17 being a pair of feeding points of the antenna conductor 21 are provided to a window glass 12 with a defogger 30, the antenna conductor 22 is electrically connected to the defogger 30, and a capacitive coupling part 10 with capacitive coupling formed therein is provided in series to a ground path for connecting the defogger 30 to a vehicle body side ground via the ground side feeding part 17.
