Abstract
The present invention provides a heat-reflecting windshield that includes a laminated glass sheet and a detecting device for optically detecting a target object such as water droplets. The laminated glass sheet includes a first glass sheet, a heat-reflecting film formed on the first glass sheet, an intermediate film and a second glass sheet. The detecting device is disposed on a main surface of the laminated glass such that a light-emitting element and a light-receiving element in the device are arranged in a predetermined region of the main surface, and the predetermined region is rubbed by a windshield wiper. The heat-reflecting film includes at least three dielectric layers and at least two metal layers, and the heat-reflecting film is not formed in said predetermined region.
