Provided is a process for producing an automotive glass with a member in a highly efficient and space-saving manner. The process for producing an automotive glass with a member comprises bonding together an adhesion surface of an adherend and an adhesion surface of an automotive glass using an adhesive, and then curing the adhesive using a superheated steam generator, thereby attaching the adherend to the automotive glass; wherein the superheated steam generator comprises (1) a boiler part for generating steam, (2) a superheating unit for superheating the steam generated in the boiler part, and (3) a superheated steam vessel equipped internally with one or more heaters and one or more superheated steam outlets for discharging the superheated steam supplied from the superheating unit; and wherein the step of curing the adhesive is performed by covering the adherend placed on the automotive glass with the superheated steam vessel, spraying the superheated steam from the one or more superheated steam outlets to the adherend, and then spraying dry gas.
