說明書

This windshield is provided with a trapezoidal laminated glass 10, and is installed in a vehicle body in an inclined state. The laminated glass 10 includes an outer glass plate 11, an inner glass plate 12, and an interlayer 13 disposed therebetween. Then, a blocking layer 4 is layered on the vehicle interior side of the inner glass plate 12, and the field of view from the outside of the vehicle is blocked by this blocking layer 4. Also, the blocking layer 4 is provided with an opening 43, and images of the outside of the vehicle can be taken by the imaging device 2 disposed inside the vehicle via the opening 43. That is, this opening 43 constitutes an imaging window. Also, a frame-shaped bracket 6 is fixed to the blocking layer 4 of the inner glass plate 12, and the imaging device 2 is attached to the bracket 6. Because the bracket 6 is fixed to the blocking layer 4 that is formed in a frame shape, the bracket 6 cannot be seen from the outside of the vehicle. Furthermore, a heating wire 8 is disposed on the inner glass plate 12 so as to pass through the opening 43. Hereinafter, constituent elements will be described in detail.
