PROBLEM TO BE SOLVED: To provide a glass antenna the frequency characteristic of the reception sensitivity for an FM band of which can be enhanced without the need for direct connection of a cross wire to a heater wire at the lowermost end. SOLUTION: An interval between the lowermost end heater wire and a wire right above the hater wire is selected wider than that between the other heater wires. In the case that the frequency characteristic of the reception sensitivity is largely changed depending on whether or not the cross wire 41 is connected to the lowermost end heater wire #14, the tip of the cross wire 41 is formed to be an L-shaped element section 41a, the L-shaped element section 41a is placed closely to the lowermost end heater wire #14 to capacitively couple the L-shaped element section 41a with the lowermost end heater wire #14. Then the intermediate frequency characteristic of the reception sensitivity can be obtained between those of an antenna pattern where the cross wire is directly connected to the lowermost end heater wire #14 and an antenna pattern where the cross wire is not connected to the lowermost end heater wire #14, and the reception sensitivity for the FM band is not deteriorated but can be made flat.
