The present invention than convenient-to-use, cost is lower, suitable for mass production, gentle by your skin, to provide a leak-proof material for disposable diapers (diapers). [SOLUTION] The leak-proof material is a leak-proof film layer 1 arranged on the top layer, and a nonwoven fabric layer 2 disposed on the bottom layer, the leak-barrier film layer 1 is partially or entirely on the surface of the nonwoven fabric layer 2 The result is coupled to the at least one through-hole areas 21 to nonwoven fabric layer 2 is disposed, a through hole area 21 are arranged at equal intervals on the nonwoven fabric layer 2 and is formed from a plurality of through-holes 211 that penetrate. .BACKGROUND【課題】より便利に使用でき、コストがより低く、大量生産に向き、お肌によりやさしい、使い捨ておむつ(紙おむつ)用の防漏素材を提供する。【解決手段】この防漏素材は頂層に配置される防漏フィルム層1と、底層に配置される不織布層2とを備え、防漏フィルム層1が不織布層2の表面に部分的に又は全部に結合されてなり、不織布層2に少なくとも一つの貫通孔エリア21が設置され、貫通孔エリア21は不織布層2に等間隔に配置され、貫通する複数の貫通孔211から形成される。【選択図】図3
