Vehicle window glass and method for manufacturing vehicle window glass
To provide a vehicle window glass which is not susceptible to cracks, and a method for manufacturing the vehicle window glass. A vehicle window glass 1 of the present invention is provided with: a glass plate 11 ; a color ceramic layer 12 , which is formed on the surface of the glass plate 11 , and has a thickness more than 10 μm but equal to or less than 25 μm; and an electrically conductive layer 13 , which is formed on the surface of the color ceramic layer 12 , and has silver as a main component. The electrically conductive layer 13 and a terminal electrically connected to the electrically conductive layer 13 are connected to each other using a lead-free solder 14 . In the vehicle window glass 1 of the present invention, since the thickness of the color ceramic layer 12 is more than 10 μm, the glass plate 1 is not susceptible to cracks.
1. A vehicle window glass, comprising:
a glass plate;
a color ceramic layer formed on the surface of the glass plate and having a layer thickness of more than 10 μm and less than or equal to 25 μm;
an electrically conductive layer formed on the surface of the color ceramic layer, containing silver as a main component, and having a layer thickness of 7 μm to 8 μm;
a lead-free solder; and
a terminal through which electricity is conducted to the electrically conductive layer;
wherein the glass plate, the color ceramic layer, the electrically conductive layer, the lead-free solder and the terminal are laminated in this order.
2. The vehicle window glass according to claim 1 , wherein the thickness of the color ceramic layer is 18 μm or more.
3. The vehicle window glass according to claim 1 , wherein the electrically conductive layer is formed by performing coating with one sheet of screen.
4. The vehicle window glass according to claim 1 , wherein the lead-free solder is a Sn—Ag-based lead-free solder or a Sn—Ag—Cu-based lead-free solder.
