The invention relates to a glass product with electrically heated surface and a method of its manufacture. A method of manufacturing a glass product with electrically heated surface comprises the steps of: producing a substantially transparent substrate; applying a substantially transparent electroconductive layer to the substrate; and forming in the electroconductive layer at least one section with electrically insulated zones separated by electroconductive strips, which at least partially deviate from the longitudinal direction of the section and consist of straight and/or curved portions having substantially the same width w within one section, the width being selected for a specified configuration of electrically insulated zones as a function of desired total resistance R.sub.total of the section, consisting of combination of resistances R.sub.N of the strip portions, wherein resistance R.sub.N of each strip portion is determined from the equation: where R.sub.□ is the specific resistivity of the electroconductive layer; w is the width of the strip, and l.sub.N is the length of each portion of the strip.

A planar heating element for a window includes a resin base having a flat or curved surface, a heating element formed of a conductive sheet having a uniform specific resistance and provided to spread in the form of a planar shape along the shape of the surface of the resin base, and conductive current supply portions provided to extend in the form of bands on opposite ends of the heating element, so as to allow a current to pass through the heating element.
