    • PROBLEM TO BE SOLVED: To obtain a sufficient water absorption capacity so as to miniaturize an absorber and also to improve flexibility, in an absorber containing water absorbable fiber, by incorporating a specified amount of a softening component into a water absorbable fiber having a specified absorption capacity of a physiological saline solution. SOLUTION: The water absorbable fiber 1 having the absorption capacity of the physiological saline solution of 30-120 times of a fiber weight is incorporated in a body fluid absorber used for a disposable diaper, a sanitary napkin, etc., and 5-50wt.% softening component is incorporated in this water absorbable fiber 1. For the water absorbable fiber 1, those having physiological saline solution absorbing capacity of 1-30g per 1cm is used. As the result, the absorber is miniaturized since an uneven distribution and falling are hardly caused and the absorber is excellent in handling and absorption. And the absorber is formed by forming a conjugated body 5 by interposing a layer of the water absorbable fiber 1 between the layer of a water insoluble hydrophilic fiber 2 and laminating a water permeable sheet on the surface of the conjugated body 5 and laminating a water impermeable sheet on a rear surface of the conjugated body 5.
