Abstract:
1. An absorbent article having a pad configuration, the article comprising: a first layer, a second layer, superabsorbent polymer particles interposed between the first and second layers of which at least one is water-permeable, wherein at least one of opposed surfaces of the first and second layers in the article is formed with absorbing regions coated with a hot melt adhesive for fixation of the superabsorbent polymer particles, and a sealing region coated with a hot melt adhesive for sealing and surrounding the absorbing regions, each of the absorbing regions defines an existence region in which a required mass per unit area of the superabsorbent polymer particles bonded to the at least one of the opposed surfaces of the first and second layers with the hot melt adhesive for fixation of the superabsorbent polymer particles exists, the sealing region defines a non-existence region in which the opposed surfaces of the first and second layers are joined to each other with the hot melt adhesive for sealing, and an amount of the superabsorbent polymer particles corresponding to the required mass per unit area of the superabsorbent polymer particles in the absorbing region does not exist, the superabsorbent polymer particles have a water-absorption speed AS the second superabsorbent polymer particles are bonded to a remainder of the opposed surfaces of the first and second layers with a second hot melt adhesive for fixation of the second superabsorbent polymer particles.
