A biaxial stretchable elastic laminate is provided, which includes a biaxial elastic film, and a first uniaxial elastic fiber web layer and a second uniaxial elastic fiber web layer, wherein the first uniaxial elastic fiber web layer and the second uniaxial elastic fiber web layer are respectively laminated on the two opposite surfaces of the biaxial elastic film, and the stretchable direction of the first uniaxial elastic fiber web layer and the stretchable direction of the second uniaxial elastic fiber web layer are orthogonal to each other, and the elastic coefficients of the first uniaxial elastic fiber web layer and the second uniaxial elastic fiber web layer are lower than the elastic coefficient of the biaxial elastic film.
