<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid absorbent sheet which prevents the sticking of a resin melt to a needle for forming pores, and can improve productivity. <P>SOLUTION: In the method for manufacturing the liquid absorbent sheet 10 having a hydrophobic layer 11 and a liquid absorbent layer 12 with liquid absorbency, and pores 13 formed at least on the hydrophobic layer 11, the method includes: a layering step of forming a laminate of the hydrophobic layer 11 and the liquid absorbent layer 12; and a pore forming step of forming the pores 13 by thermal perforation from a side of the liquid absorbent layer 12 of the laminate. A heating temperature in the pore forming step is at least the melting point of the thermoplastic resin. <P>COPYRIGHT: (C)2013,JPO&INPIT |
