Abstract
(EN)
The disclosed disposable diaper (1) is provided with an absorbent body (4) that contains an oblong absorbent core (40) and comprises an abdominal part (A), crotch (C) and back (B). The absorbent core (40) has a high basis weight part (41) in the center of the width direction of the crotch (C) and low basis weight parts (42) of lower basis weight than said high basis weight part (41) on both sides of the high basis weight part (41). The high basis weight part (41) has a central fold-inducing part (43) that is configured from a slit, groove or fiberless region that extends in the longitudinal direction of the absorbent core (40). Each low basis weight part has a side fold-inducing part (44) that is configured from a fiberless region. On the abdominal (A) side of the absorbent core (40) in the longitudinal direction, the central fold-inducing part (43) extends past the ends of the side fold-inducing parts (44) and on the back (B) side of the absorbent core (40) in the longitudinal direction, the side fold-inducing parts (44) extend past the end of the central fold-inducing part (43).
