Abstract:
1. An absorbent article having a first direction and a second direction orthogonal to the first direction, said absorbent article comprising: two sheet members, at least one of which is liquid permeable; and superabsorbent polymer particles interposed between facing surfaces of the two sheet members; wherein one of the facing surfaces of the two sheet members is coated with a first hot melt adhesive, the superabsorbent polymer particles are bonded to the one of the facing surfaces with the first hot melt adhesive in absorbing areas extending in the second direction and arranged at predetermined intervals in the first direction, the facing surfaces of the two sheet members are further bonded to each other with a second hot melt adhesive in sealing areas outside the absorbing areas, and the sealing areas are substantially free of the superabsorbent polymer particles, the absorbing areas adjacent to each other in the first direction have opposite edges by intermediary of the sealing areas, and at least one of the opposite edges is defined by a wavy line having crest portions and trough portions in the second direction, the superabsorbent polymer particles have an absorption speed of AS second superabsorbent polymer particles having an absorption speed of AS the second superabsorbent polymer particles are bonded to the other one of the facing surfaces with a further hot melt adhesive.
