A method for producing laminated glass for automobile windows, the method comprising:
- heating and bend forming two glass plates;
- and
- bonding together the two bend-formed glass plates via an interlayer film,
- wherein the method further comprises scratching that is performed on a concave surface of at least one of the two glass plates, after the bend-forming,
- wherein the bonding includes:
- obtaining a preliminary pressure-bonded body by performing preliminary pressure bonding on a laminate in which the two glass plates are laminated via the interlayer film under atmospheric pressure or reduced pressure, and
- obtaining laminated glass by performing main pressure bonding on the preliminary pressure-bonded body at a high temperature and under high pressure, and
- wherein the scratching is performed on a concave surface of the laminate together with the preliminary pressure-bonding.
