The present invention provides a bodily fluid containment structure that the bodily fluids once received therein should not leak out from the structure even when the wearers weight is exerted thereon or the wearer changes his or her posture and to provide a wearing article including this containment structure.A chassis 2 is provided on outer surface of an outer sheet 9 with a bodily fluid containment structure 15. In a crotch region 7, an inner liner 8 and an outer sheet 9 are formed with through-hole 16 extending through these sheets. Inner and outer sheets 18, 19 of the containment structure 15 are bonded to each other along outer peripheral edges thereof to form an envelope. The inner sheet 18 is formed with an opening 25 and, on both sides of this opening as viewed in a longitudinal direction Y, front and rear containment regions adapted to contain bodily fluids are formed. The opening 25 of the containment structure 15 is aligned with the through-hole 16 extending through the inner liner 8 and the outer sheet 9 and the peripheral edge of the opening 25 is bonded to the outer sheet 9 by first bonding means 49. A bonded region 28 is formed between the inner and outer sheets 18, 19 to bond these sheets to each other. The bonded region 28 comprises a plurality of bonded line segments and first channels are formed by these bonded line segments.
