Abstract
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 μΩcm, 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.
