Abstract
An electrically heatable windshield comprises two glass plates bonded to each other with an interlayer therebetween and a transparent conductive layer formed at contacting surface between one of the glass plates and the interlayer so that the windshield is heated by supplying a current to the transparent conductive layer through a bus bar for feeding power. A colored layer such as a ceramic color print is formed at the peripheral portion of the surface, in contact with the interlayer, of at least one of the glass plates. The bus bar is formed on the colored layer without expanding. A transparent protective layer is formed so as to cover the edge portion of the colored layer which is near the center of the glass plates, and the transparent conductive layer is formed over the transparent protective layer.
