摘要

Highly permeable and water resistant barrier sheet, comprises a porous buffer sheet and a water resistant nonwoven cloth of 100 mmH 2O or higher in water resistance connected integrally with each other and combined with a permeable sheet-like absorber to form an absorbing core. Highly permeable and water resistant barrier sheet, comprises a porous buffer sheet and a water resistant nonwoven cloth of 100 mmH 2O or higher in water resistance connected integrally with each other and combined with a permeable sheet-like absorber to form an absorbing core so as to make an absorber product highly permeable, wherein the porous buffer sheet is a perforated film formed desirably in an irregular structure having funnel-shaped perforated structures with top and bottom parts different in diameter from each other and, when the diameter thereof on the shorter diameter side is 1mm or shorter when a hole is approximated in a complete round shape and the number of holes is 20/cm 2or more.
