Abstract

A slide valve apparatus includes a first member having a first fluid channel for allowing a fluid to flow therethrough, a second member sliding along the first member and having a second fluid channel formed in a manner to communicate with the first fluid channel, and a first elastic membrane formed in the sliding surface along which the second member and the first member slide relative to each other and having a first communicating hole communicating with the first fluid channel. In manufacturing the slide valve apparatus, a gas is spurted from the open edge of the first fluid channel in at least a stage between the start up of the step of forming the elastic membrane and the end of the step of baking the elastic membrane so as to form in the elastic membrane the communicating hole communicating with the first fluid channel.
