<；P>；PROBLEM TO BE SOLVED: To provide sanitary goods such as a disposable diaper using a recyclable absorber, various types of mat or various types of sheet for a person or an animal, and a packaging material. <；P>；SOLUTION: The absorber is equipped with a first water-absorbing paper layer part, a second water-absorbing paper layer part, and a water-absorbing material layer or a water-absorbing material layer part containing thermal polymeric gel and pulp, which is positioned between the layer parts； and the first water-absorbing paper layer part, the water-absorbing material layer part and the second water-absorbing paper layer part are integrally formed. A composition of the first water-absorbing paper layer part, the second water-absorbing paper layer part, the pulp, the thermal polymeric gel and a water-absorbing resin is used as the water-absorbing material layer part. Thus, the absorber after use can be easily dehydrated by virtue of the water absorbency of the pulp by being heated at a temperature as high as/higher than a temperature sensing point of the thermal polymeric gel. Additionally, a soluble component is removed by having the absorber after use soaked in water so as to absorb the water, and the absorber after use can be reused by being heated and dried at the temperature as high as/higher than the temperature sensing point. <；P>；COPYRIGHT: (C)2006,JPO&NCIPI
