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. When observing the laminated glass in both internal and external environments, this neutralizes the haze of the dimming functional layer, making the white haze of the dimming functional layer less noticeable. This improves the appearance of white fogging and enhances the consistency of internal and external observation results of the laminated glass, thus providing a better two-way observation experience for passengers. Furthermore, both transmittance T1 and T2 are greater than 15%, preventing them from being too low and ensuring that the overall transmittance of the laminated glass is not too low, which would affect the dimming effect.
