PROBLEM TO BE SOLVED: To provide the production method of laminated glass capable of reducing the fraction defective in the product of laminated glass. SOLUTION: A pair of plate glasses 11 and 12 and an interlayer film 15 are washed with a prescribed washing liquid. The interlayer film 15 is held between the washed pair of plate glasses 11 and 12. Next, the pair of plate glasses 11 and 12 with the interlayer film 15 held in-between are temporarily taped each other at the four square corner parts using a tape 20. While the pair of flat glasses 11 and 12 and the interlayer film 15 subjected to the temporary tacking in the step S3 are heated at 70 to 80°C, the same is passed through two pairs of pressing rolls 40, thus temporary press-fixing is performed while air remaining between the plate glasses 11 and 12 and the interlayer film 15 is removed. Further, the temporarily press-fixed laminated glass 10 is pressurized under heating in a pressure resistant oven 50 where pressure is about 1.2 MPa and temperature is about 130°C, and is subjected to normal press-fixing under heat and pressure.
