1. Window glass for vehicle, comprising:
- a glass plate;
a dielectric;
a conductive film arranged between the glass plate and the dielectric; and
an antenna conductor having electrodes provided on a surface of the dielectric on a side opposite from the conductive film,wherein the conductive film is formed with a slot having a first end part that opens at a peripheral edge part of the conductive film,the antenna conductor includes a loop-shaped antenna element which the electrodes serve as a feeding point,projections of the electrodes on a side of the glass plate are located at positions not overlapping the conductive film, anda projection of the loop-shaped antenna element on the side of the glass plate forms a crossover part that crosses the slot.

Abstract
Window glass for vehicle may include an antenna conductor having electrodes provided on a surface of a dielectric on a side opposite from a conductive film. The conductive film may include a slot with a first end part that opens at a peripheral edge part of the conductive film. The antenna conductor may include a loop-shaped antenna element which electrodes serve as a feeding point, and projections of the electrodes onto a glass plate are located at positions not overlapping the conductive film, and a projection of the loop-shaped antenna element onto the glass plate forms a crossover part that crosses the slot.
