PROBLEM TO BE SOLVED: To provide an automotive high frequency glass antenna which improves antenna gain for digital terrestrial television broadcasting. SOLUTION: A plurality of heater wires are provided with a plurality of circumvention parts 1. The heater wire is provided with an entry part 10 to be connected to the circumvention part 1. Both ends of the entry part 10 and both ends of the circumvention part 1 are connected with one pair of connecting wires 9. When the smaller one of shortest distance between the pair of connecting wires 9, and shortest distance between the both ends of the entry part 10 is W<SB>e</SB>, the maximum width of the circumvention part 1 in horizontal direction is W<SB>r</SB>, and received frequency wavelength in the air isλ<SB>0</SB>, ä(W<SB>r</SB>-W<SB>e</SB>)/2}=L<SB>1</SB>and L<SB>1</SB>≥0.0053×λ<SB>0</SB>are satisfied.
