PROBLEM TO BE SOLVED: To uniformly heat at least the central region of a pane and further to impart a defogging function even to the triangular region on both sides by providing plural metallic heating wires in the intermediate film of a laminated glass longitudinally and squarely and forming a heating transparent electrically conductive film almost over the whole face of whichever sheet glass. SOLUTION: Two sheet glasses are joined through an intermediate film of polyvinyl butyral or the like, to form a laminated glass 1, plural metallic heating wires 3 are provided in the intermediate film longitudinally and nearly squarely, a heating transparent electrically conductive film 2 is formed almost over the whole face of whichever sheet glass, and a defogging glass for vehicles is obtained. The conductive film is formed on the concave face (inward) of the sheet glass of the laminated glass 1 outside the vehicle, and the metallic wire is embedded in the intermediate film inside the vehicle to avoid contact of both. Such metallic wires as tungsten wire and copper wire are appropriately used as heating wire, and the metal oxide film of SnO2, In2O3, ITO or the like, are appropriately used as the conductive film.
