PROBLEM TO BE SOLVED: To use a wide range of an absorbent pad or an absorbent core for absorbing moisture of excreta.;SOLUTION: A body part 2 of a disposable diaper 1 has an almost sheet-like shape where an absorbent core 22 is arranged between a back sheet 23 and a top sheet 21 and has a front part 201, a crotch part 202, and a rear part 203 in a longitudinal direction in order. A pair of connection parts 4 fitted to both side parts of the rear part 203 are sealed on an outer surface of the front part 201, so that both end parts are connected to both end parts of the front part 201. An IC chip and an IC tag 5 having an antenna are fitted to a detection position on the top sheet 21 of either the rear part 203 or the front part 201. The IC tag 5 can detect moisture at the detection position. In the disposable diaper 1, before moisture is detected by the IC tag 5, a wide range of an absorbent pad or an absorbent core 22 can be used for absorbing moisture of excreta.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
