|Title:||ULTRASONIC WELDING METHOD FOR SEPARATORS|
The present invention addresses the problem of providing an ultrasonic welding method for separators, by which two separators each having a heat resistant layer can be welded together while the heat resistant layers are opposed to each other such that the strength of bonding therebetween is relatively high. The ultrasonic welding method for separators according to one aspect of the present invention comprises: supporting, by a support member, at least two separators each having a resin layer and a heat resistant layer formed on the resin layer such that the heat resistant layers are opposed to each other; and moving, relative to the at least two separators, a vibration member that ultrasonically vibrates upon contact, in a dot pattern, with the separators, while pressing the vibration member against the separators.
