Definitions
- the present invention relates to an absorbent body used for absorbent articles such as a urine pad (including a light incontinence pad), a sanitary napkin, a disposable diaper, an absorbent article provided with the same, and a method for producing the same.
- Patent Documents 1 to 4 disclose absorbent articles having such an absorber.
- the water absorbent resin is arranged between the sheet members.
- the water absorbent resin is finely granular, for example, the water absorbent resin is bonded and fixed to the sheet member with an adhesive or the like.
- it is difficult to fix all the water-absorbing resins and there is a case where the water-absorbing resin is dropped from between the sheet members.
- the pulp fiber is not arranged between the sheet members, the water absorbent resin is not entangled and held in the pulp fiber, and the water absorbent resin is easily dropped.
