Abstract
An absorbent article is formed by interposing superabsorbent polymer particles between overlapping two sheets. The pad-shaped absorbent article is composed of superabsorbent polymer particles bonded to the sheet with a hot melt adhesive, absorbing areas where the sheets are not bonded and sealing areas where the sheets are bonded together and surrounding the absorbing areas. Opposed two adjacent bonding areas of the absorbing areas have the sealing areas in between and facing edges which has the sealing areas in between. One of the facing edges is defined by a wavy line having crest and trough portions.
