An elastic film of the present invention has an outermost layer (A) containing a elastomer and a amide-based compound. The amide-based compound is at least one selected from the group consisting of saturated fatty acid monoamide, saturated fatty acid bisamide and the unsaturated fatty acid amide. In the elastic film of the present invention, it is preferable that the elastomer is at least one selected from the group consisting of styrene-isoprene-styrene block copolymers and propylene-based elastomers.本發明之彈性膜,係以含彈性體及醯胺系化合物之層(A)作為最表層。前述醯胺系化合物,係選自於由飽和脂肪單醯胺、飽和脂肪雙醯胺及不飽和脂肪醯胺所構成群組中的至少1種。本發明之彈性膜中,前述彈性體,以選自於由苯乙烯-異戊二烯-苯乙烯嵌段共聚物及丙烯系彈性體所構成群組中的至少1種較佳。
