To provide a vehicle window glass and a manufacturing method of a vehicle window glass, which can suppress generation of cracking and local deformation on a glass plate.SOLUTION: A vehicle window glass comprises a vehicle outer glass, a vehicle inner glass, and a laminated glass made of an interlayer sandwiched between the vehicle outer glass and the vehicle inner glass. The vehicle inner glass comprises a notch formed at an edge of a vehicle interior lower side so as to penetrate in a plate thickness direction of the vehicle inner glass. When the length of the vehicle interior lower side is L and the shorter distance among distances between a corner of the vehicle interior lower side and a notch end of the notch on the side closer to the corner is S, S/L<0.24 is satisfied.SELECTED DRAWING: Figure 9
