| 摘要 |
A laminating method of thermoplastic resin members which comprises, superposing a (n-1)th thermoplastic resin plate on a (n-2)th thermoplastic resin plate, bonding the (n-1)th thermoplastic resin plate to the (n-2)th thermoplastic resin plate by ultrasonic welding with an ultrasonic horn having projections and indentations on the pressure face from the upside of the (n-1)th thermoplastic resin plate wherein n is an integral number of more than 2, repeating the above process when n is more than 3, superposing a nth thermoplastic resin plate on the welded (n-1)th thermoplastic resin plate, and bonding the nth thermoplastic resin plate to the (n-1)th thermoplastic resin plate by ultrasonic welding with an ultrasonic horn having a flat pressure face from the upside of the nth thermoplastic resin plate.
