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.
