melting point (Tm-D) being from 0 to 120° C., which is defined as a peak top of a peak observed on the most high temperature side of a melt endothermic curve obtained by maintaining at −10° C. for 5 minutes and increasing in temperature at 10° C. per minute in a
nitrogen atmosphere with a differential scanning
calorimeter (DSC); and(b) a stereoregularity index ([mm]) being from 50 to 90% by mol;(2) an elastic nonwoven fabric and a
