<P>PROBLEM TO BE SOLVED: To provide an elastic laminate sheet which is hardly broken in spite of repeated stretches and demonstrates a practically sufficient retention when put on a main part of sanitary goods, etc. <P>SOLUTION: The elastic laminate sheet includes an elastomer layer and a laminate with a nonwoven fabric prepared on at least one surface of the elastomer layer, wherein the elastic laminate sheet has a low elastic laminate member and a high elastic laminate member both of which constitute the laminate and are arranged alternately in one direction in a way that a first joining region and a second joining region reside in both of the low elastic and high elastic laminate members, wherein the elastomer layer and the nonwoven fabric join in the first joining region, the elastomer layer and the nonwoven fabric join more weakly in the second joining region than in the first joining region, the total area of the first joining region is larger in the low elastic laminate member than in the high elastic laminate member, a ratio of elastic modulus of low elastic member to that of the high elastic laminate member is ≥1 and ≤7.5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
