Abstract:
1. A heat-reflecting windshield comprising a laminated glass sheet, a detecting device for optically detecting a target object, and a ceramic mask that is provided on a periphezy of the windshield, the detecting device having a light-emitting element and a light-receiving element, the laminated glass sheet comprising a first glass sheet, a heat-reflecting film formed on the first glass sheet, an intermediate film and a second glass sheet, wherein the detecting device is disposed on a main surihee of the laminated glass sheet such that the light-emitting element and the light-receiving element are arranged in a predetermined region of the main surface, and said predetermined region is rubbed by a windshield wiper, wherein the heat-reflecting film comprises a first dielectric layer, a first metal layer, a second dielectric layer, a second metal layer and a third dielectric layer, and the heat-reflecting film is not formed in said predetermined region, wherein said predetermined region comprises an opening in the heat-reflecting film, is surrounded by the heat reflecting film, and includes a detecting region that is surrounded by the ceramic mask, wherein the ceramic mask covers the edge of the heat-reflecting film around the detecting region, and wherein the detecting device detects the target object in the detecting region.
