PROBLEM TO BE SOLVED: To provide an elastic laminate excellent in handleability and blocking resistance and an article including the elastic laminate, and an elastic laminate elongation in which the elastic laminate is elongated beforehand and an article including the elastic laminate elongation.SOLUTION: An elastic laminate having an olefin-based resin layer on at least one side of an elastomer layer. In an S-S data figure (Figure 2) of an operation of elongating the elastic laminate to an elongation rate of 400% at tensile speed of 1,000 mm/min, and then returning the elongation of the elastic laminate to an elongation rate of 0% at the tensile speed of 1,000 mm/min, the elastic laminate has an upper yield point while the elastic laminate elongates at the elongation rate of 0-100% and a lower yield point while the elastic laminate elongates to the elongation rate of 400% from the upper yield point, and has a difference between yield stresses of the upper yield point and the lower yield point of 0.05 N/30 mm width or more. The olefin-based layer contains a non-elastomeric olefin resin containing a homopolymer of α-olefin, and the elastomeric olefin resin contains an olefin-based elastomer.SELECTED DRAWING: Figure 2 |
