Abstract (en)
A vehicle window glass according to the present invention includes a glass plate, a defogger formed on the glass plate and having a pair of bus bars and a plurality of horizontal heating wires that join the pair of bus bars, at least one vertical element provided in the defogger and intersecting at least one of the horizontal heating wires, and a first antenna element formed on the glass plate and capacitively coupled to the defogger, the first antenna element being configured to receive broadcast waves having a frequency range of wavelengths λ<sub>1</sub>to λ<sub>2</sub>that is higher than an FM frequency range, and Pmin<α·λ<sub>1</sub>/2 being satisfied, where Pmin is a smallest distance, out of the distance between one of the bus bars and the vertical element and the distance between the vertical antennas, and α is the shortening coefficient of wavelength of the glass plate.
