Abstract
A windshield glass including a transparent conductive film and bus bars for feeding electricity thereto. In the windshield glass, at least one film-free portion is formed in the transparent conductive film and is arranged so as to lie in at least a part of a wiper blade stopping area in the windshield glass or is arranged in the vicinity of the area. This configuration relatively increases the amount of electric current passing through a unit area of the transparent conductive film at least in a part of the wiper blade stopping area.
Claims19
A windshield glass comprising:
- at least two glass sheets bonded to each other with a thermoplastic resin film interposed therebetween;
- a transparent conductive film formed on one main surface of one of the glass sheets;
- and bus bars formed on the one main surface for feeding electricity to the transparent conductive film,
- wherein the transparent conductive film comprises at least one film-free portion in which the transparent conductive film is not formed, the at least one film-free portion being arranged so as to lie in at least a part of a wiper blade stopping area on the windshield glass or being arranged in the vicinity of the area, and
- wherein the at least one film-free portion is arranged so that an amount of current passing through a unit area of the transparent conductive film increases at least at a part of the wiper blade stopping area as compared with a case of the absence of the at least one film-free portion.

A windshield glass comprising:
- at least two glass sheets bonded to each other with a thermoplastic resin film interposed therebetween;
- a transparent conductive film formed on one main surface of one of the glass sheets;
- and bus bars formed on the one main surface for feeding electricity to the transparent conductive film,
- wherein the transparent conductive film comprises at least one film-free portion in which the transparent conductive film is not formed, the at least one film-free portion serving as an electromagnetic wave passing portion and being arranged outside an area surrounded by a ceramic print that is formed on one main surface of one of the glass sheets.
