Abstract
An electrically heating windshield glass has two glass plates; a polyvinylbutyral sheet interposed between the two glass plates; a pair of bus bars provided at peripheral portions of the glass plates and between them; and a number of tungsten wires connected between a pair of the bus bars. The diameter of the tungsten wires or the space between adjacent tungsten wires is continuously and/or stepwisely changed in response to a change of the distance between the bus bars.
