To provide a vehicle window glass, in which heater wires and a conductor wire, such as an antenna, intersect, and a mounting structure for the window glass for a vehicle. The heater wires are not noticeable and have a good appearance. A window glass for a vehicle, comprising a glass main body, a plurality of heater wires formed to extend in a horizontal direction when mounted to a vehicle, and an antenna wire formed to intersect at least one of the heater wires, wherein the smallest line width 'a' of the heater wires is at most 0.4 mm, and the largest line width 'b' of the antenna wire is smaller than the line width &#x201c;a&#x201d; in a range of intersection of the antenna wire and the heater wires extending from one end of the antenna wire to the other end of the antenna wire.

Window glass for vehicle and mounting structure for same

The present invention is concerned with a windowpane for vehicles including a glass sheet, a conductor layer which is formed on the surface of the glass sheet by sintering a silver paste containing a silver powder and a glass frit and which has at least a strip part and a terminal connection part connected to the strip part, and a connection terminal soldered onto the terminal connection part with a lead-free solder alloy, in which the conductor layer has a specific resistance of from 2.5 to 6.5 &#x3bc;&#x3a9;cm, the strip part has a line width of not more than 0.35 mm, the lead-free solder alloy consists essentially of tin and silver and has a content of tin of 95% by mass or more, and cracking is not caused on the glass sheet even after elapsing 500 cycles in a prescribed thermal shock test; and a method for producing same.
