Zusammenfassung:	PURPOSE:To perform fusion bonding good in air-tightness and water-tightness, by covering the upper side of the abutted part of two thermoplastic resin sheets with a thermoplastic resin belt provided with a large number of piercing holes, and pressing the covered part by a hot iron. CONSTITUTION:A plastic belt 1 provided with a large number of piercing holes 2 is placed on the abutted part 6 of two thermoplastic resin sheets 4, 5 and a hor iron is brought into contact with the upper surface of the belt 1. The upper surface of the belt 1 is heated and, at the same time, the radiant heat of the hot iron reaches the plastic sheets under the belt through the piercing holes 2 to heat and soften said plastic sheets. In this state, the hot iron is pressed to perform fusion bondong.
