PURPOSE: To solve such problems in sanitary napkins and panty liners, that the rear surfaces of back sheets are provided with tacky adhesive parts for preventing the slipping to underwear, or the like, but when these absorptive articles are made hydrolyzable, the decomposition of the tacky adhesive parts delay and therefore the back sheets float in the state of relatively large areas within a septic tank. CONSTITUTION: The rear surface of the back sheet 20 is provided with the tacky adhesive parts 30 by dispersing spacings between a longitudinal direction and a transverse direction. The exposed parts 20a of the sheet are made continuous as a whole and are so formed as to arrive at edges 1f and 1e of the absorptive article. The spacings between the tacky adhesive parts 30 are previously set longer than the maximum fiber length of the sheet. Consequently, when the exposed parts 20a of the sheet are collapsed by water, the tacky adhesive parts 30 are dispersed so as to part from each other. The back sheet may thus be finely dispersed in the water.
