A window glass for vehicle includes a glass plate having a transmissive region transmitting visible light, and a light shielding film shielding visible light; a dielectric having a first surface and a second surface; a planar conductor arranged between the glass plate and the first surface of the dielectric; positive and negative electrodes connected to the planar conductor; one or more feeding electrodes and one or more grounding electrodes arranged on the second surface of the dielectric. The planar conductor generates heat by an electric voltage applied between the positive and negative electrodes. The feeding electrodes and the grounding electrodes are arranged to face the planar conductor via the dielectric so that the planar conductor receives at least electromagnetic waves of a VHF band. The positive electrode, the negative electrode, the feeding electrodes and the grounding electrodes are arranged to overlap with the light shielding film in a planar view.
