Abstract
An object of the present invention is to provide a stretchable structure that has stretchability together with high stress relaxation properties, and provides fit feeling with less tightening by recovering slowly after stretching. The object is achieved by a stretchable structure having the following characteristics: a tensile permanent set (PS) of 1% or more and 50% or less, wherein the tensile permanent set (PS) is a value obtained 10 minutes after 150% elongation at a tension rate of 200 mm/minute in accordance with JIS K7127, and a ratio PS/PSof 1.10 or more, wherein the PSis the tensile permanent set obtained 10 minutes after the elongation and the PSis the tensile permanent set obtained 1 minute after the elongation.
