The present invention I provide an excellent stretchable sheet material to stretching force and penetration strength. And A embossed portions 15 nonwoven fabric 11 which is interspersed and are arranged in one direction without intersecting with each other, and a plurality of elastic filaments 13 are joined in a non-stretched state to the nonwoven fabric 11 over the entire length, the nonwoven fabric 11 has a non-embossed portion 16 that does not exist the embossed portion 15 along the one direction, said non-woven fabric 11 between the embossing unit 15 without destruction of the embossed portion 15 can be extended Yes, the elastic filament 13 is the elastic sheet 10 non-embossed portion 16 and are joined. .BACKGROUND【課題】伸縮力と突き抜け強度に優れた伸縮性シート材料を提供する。【解決手段】エンボス部15が散在された不織布11と、互いに交差せずに一方向に配列されて、全長にわたり非伸長状態で前記不織布11に接合された複数の弾性フィラメント13とを有し、前記不織布11は前記一方向に沿って前記エンボス部15が存在していない非エンボス部16を有し、前記エンボス部15の破壊を伴わずに前記エンボス部15間の前記不織布11が伸長可能であり、前記弾性フィラメント13は前記非エンボス部16と接合している伸縮性シート10。【選択図】図1
