<P>PROBLEM TO BE SOLVED: To provide a high density region containing sheet having a high density region and a low density region. <P>SOLUTION: A sheet member includes: a first sheet; a second sheet; and at least one elastic member 4 which is arranged between the first sheet and the second sheet and presents either state of a thread state, a net state, a belt state or a sheet state. In the first sheet, a plurality of unevenness regions 21, 22 in which a high density concave part and a low density convex part extending in a first direction are alternately extending along a second direction intersecting the first direction, and a groove region 23 which has no unevenness and extending along the second direction are alternately provided along the first direction. The elastic member 4 is arranged to take along the direction which is alternately formed continuously in the prescribed direction by the plurality of high density regions 21 and the plurality of low density regions 22, and at least a part in the plurality of high density region 21 are connected to the elastic member 4 of extended state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
