PROBLEM TO BE SOLVED: To provide a manufacturing method for a laminated stretchable sheet for more certainly forming air holes to an elastic sheet.
SOLUTION: The manufacturing method for the laminated stretchable sheet includes the process of forming a composite sheet by holding a thermoplastic elastic sheet between at least two nonwoven fabrics containing thermoplastic fibers and the ultrasonic jointing process for applying vibration to the overlapped parts of two nonwoven fabrics and the elastic sheet at a plurality of jointing places in the composite sheet to weld two nonwoven fabrics and the elastic sheet. In the ultrasonic jointing process, air hole to the elastic sheet only at a part of the outer edge of the jointing place.
