Abstract
A sanitary napkin has an absorbent core convexly curved upward and the absorbent core is provided on its lower side with a pad adapted to hold a curved shape of the absorbent core. The pad is formed on its upper side with a plurality of projections and continuous troughs so that the projections are bonded to the lower side of the absorbent core and the troughs form a continuous tunnel between the absorbent core and the pad. The pad thus formed improves a breathability of the sanitary napkin during its use.
