To provide a light weight laminated glass in which impact resistance and rigidity are improved.SOLUTION: There is provided a vehicular window glass comprising: a first glass plate having an S1 surface facing an external side of a vehicle, and an S2 surface at an opposite side of the S1 surface; a second glass plate having an S4 surface facing an indoor side of the vehicle, and an S3 surface at an opposite side of the S4 surface; and an intermediate film which is arranged between the first glass plate and the second glass plate, and is formed of at least one layer facing the S2 surface and the S3 surface. In the vehicular window glass, mass per 1 m2 of the vehicular window glass is 5-9 kg, and a Young modulus of all layers forming the intermediate layer is, at 23°C, 2.5 MPa to 200 MPa, and out of the first and second glass plates, at least any one is formed of a chemically strengthened glass.SELECTED DRAWING: Figure 2
