Abstract: A multi-layer sanitary napkin is provided which comprises a plurality of ordinary sanitary napkins for treating menses or leukorrhea in a single-use, each being provided with a waterproof sheet having a rim and an absorbing surface which is the top surface of an absorbing layer attached to the waterproof sheet, wherein the ordinary napkins are piled with respective absorbing surfaces thereof directed upward, and peelably joined with each other into unity at the rims by bonding, embossing or simultaneous bonding and embossing. Each of the ordinary napkins contained therein can be shaped as concave as a ship's bottom, to shape the entire figure of the multi-layer sanitary napkin in the same manner. The multi-layer sanitary napkin can further comprise pull tabs formed on either end of respective ordinary napkins, each tab being formed not so as to overlap on neighboring ones.
