Provided is a windshield that can generate heat such that information can be accurately acquired using an information acquisition device. A laminated glass according to the present invention is a windshield for an automobile to which an information acquisition device for acquiring information from the outside of a vehicle by emitting and/or receiving light can be installed, the windshield including an outer glass plate that includes a first side and a second side that is opposite to the first side, an inner glass plate that is arranged opposite to the outer glass plate and has substantially the same shape as the outer glass plate, and an intermediate film that is arranged between the outer glass plate and the inner glass plate. The windshield includes an information acquisition region that is to be located opposite to the information acquisition device and through which the light passes. The intermediate film includes at least one adhesive layer and a heat generation layer supported by the adhesive layer. The heat generation layer includes, at least in a region that corresponds to the information acquisition region, a pair of bus bars arranged such that the information acquisition region is interposed therebetween and a plurality of first heating wires that are connected in parallel so as to connect the bus bars to each other. Each of the heating wires has a wire width not larger than 10 µm.
