Abstract: In the present invention, an elastic resin material having a thermoplastic elastic resin is extruded into a sheet shape on a die and made to have a thickness that varies along the width direction, and then is cooled, to a temperature in which the elastic resin material elastically deforms, to form a sheet body that varies in thickness along the width direction, and a stretchable sheet is formed by laminating and joining base sheets. The sheet body includes at least two first and second regions adjacent to each other in the width direction, and the thicknesses of the second regions are greater than that of the first regions. In a wearable article, the stretchable sheet is disposed so that at least a portion of the second regions is closer to an opening around a body or an opening around a leg of the disposable wearable article than the first regions.

Abstract: Provided is an ultrasonic horn, the output amplitude of which can be significantly increased. An ultrasonic horn includes an input-side end section that has an input surface that receives ultrasonic vibration, and an output-side end section having an output surface that outputs ultrasonic vibration to a sheet. The output-side end section has a dimension, in the length direction, over which a side edge portion of a front abdominal section and a side edge portion of a rear dorsal section can be welded in the longitudinal direction, and is branched in a width direction that is perpendicular to the length direction by a slit that extends in the length direction. A pair of surfaces of the output-side end section, positioned on both sides of the slit, functions as the output surface through which the ultrasonic vibration is output.
