Zusammenfassung:	An absorbent article has a back sheet with an absorbent core disposed on a body side of the back sheet. On a back side of the back sheet, there is provided a substrate carrying a conductive pattern as a liquid discharge detection circuit that is able to be connected to an electric potential generator for performing liquid discharge detection. At least one or a plurality of holes is formed through the back sheet to communicate portions of the conductive pattern with the absorbent core. Longitudinally adjacent pairs of the revealed portions of the conductive pattern form liquid discharge detection zones for detecting liquid discharge in the absorbent core. The detection zones are longitudinally distributed with respect to the absorbent core.
