The side seal part S has a plurality of seal patterns 5 intermittently formed in the long direction of the diaper 1. Each of the plurality of seal patterns 5 has one side 51 extending in the diaper long direction, and when connecting line segments P', P' connecting the one sides 51 of the adjacent seal patterns 5 at a minimum distance, one straight line P is formed. The seal patterns 5 are present on both the right and left sides of the straight line P. <P>COPYRIGHT: (C)2013,JPO&INPIT |
