This application relates to a laminated glass and a vehicle. The laminated glass includes: a first glass plate, a first adhesive layer, a dimming functional layer, a second adhesive layer, and a second glass plate, which are stacked sequentially. The transmittance of the combined structure of the first glass plate and the first adhesive layer is defined as T1, and the transmittance of the combined structure of the second glass plate and the second adhesive layer is defined as T2. T1 is set to 15% to 50%, and T2 is set to 15% to 50%. Both transmittance T1 and T2 are relatively low.
