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 10M ) of 1% or more and 50% or less, wherein the tensile permanent set (PS 10M ) 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 1M /PS 10M of 1.10 or more, wherein the PS 10M is the tensile permanent set obtained 10 minutes after the elongation and the PS 1M is the tensile permanent set obtained 1 minute after the elongation. |
