| 摘要 | PURPOSE: To make it possible to absorb and hold exudate and excrement by including an absorptive layer and an expandable and contractable layer between a liquid permeable layer and a liquid impermeable layer, stretch bonding this expandable and contractable layer to other layers and forming plural pleats within the respective layers at the point of the time of slackening. CONSTITUTION: A liquid permeable body side liner 4, a liquid permeable and expandable and contractable elastomer layer 6, an absorptive medium 8 and a liquid impermeable outer cover 10 are included in an expandable and contractable and absorptive composite material 2. Next, the liner 4, the elastomer layer 6, the absorptive assembly 8 and the cover 10 are combined and bonded. The composite material 2 is so slackened that the elastomer layer 6 restores the original form from the elongated state after the bonding. The liner 4, the absorptive medium 8 and the outer cover 10 are gathered in such a manner, by which the plural pleats 14 and plural air pockets 9 are formed on both sides of the elastomer layer 6 on the inner side or the inside of the composite material 2. | ||||||
