PROBLEM TO BE SOLVED: To provide an automotive windshield, capable of achieving sufficient strength in spite of inclusion of heating conductors. SOLUTION: This automotive windshield 10 is provided with a first glass substrate 11, a second glass substrate 12 jointed with the first glass substrate 11 through a resin film 13, and silver conductors 14 formed on the first glass substrate 11 between the first glass substrate 11 and the resin film 13. The silver conductors are formed by baking conductive paste including silver powder, nickel powder, glass frit, and an organic vehicle. In a case where the silver powder is spherical, the silver powder has the minimum grain size of 0.3-1.0μm, and the maximum grain size of 1.0-3.0μm. The nickel powder is included by 1-4 wt% in the conductive paste. In a case where the silver powder has irregular form, the silver powder has the minimum grain size of 0.1-1.0μm, and the maximum grain size of 0.5-5.0μm. The nickel powder is included by 2-3 wt% in the conductive paste. COPYRIGHT: (C)2007,JPO&INPIT |
