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, formed on the surface of the glass plate 11 and having a thickness more than 10 µm but equal to or less than 25 µm, and an electrically conductive layer 13 formed on the surface of the color ceramic layer 12 and having 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.
