Claim:
A disposable diaper having a back-and-forth direction and a transverse direction being orthogonal to said back-and-forth direction, said diaper comprising: a front waist region; a rear waist region; a crotch region extending between said front and rear waist regions; a body fluid absorbent panel provided in at least said crotch region and extending in said back-and-forth direction; leak-barrier cuffs lying in a vicinity of transversely opposite side edges of said body fluid absorbent panel, respectively, and extending in said back-and-forth direction, said leak-barrier cuffs respectively having proximal edges and distal edges, wherein said proximal edges are bonded to said body fluid absorbent panel in the vicinity of the respective side edges, and said distal edges are laid inside with respect to the respective proximal edges as viewed in said transverse direction and elastically stretchable and contractible in said back-and-forth direction so as to cover a part of said body fluid absorbent panel; and said body fluid absorbent panel in said crotch region being formed with a first folding guide extending across said body fluid absorbent panel in said transverse direction so that said body fluid absorbent panel is folded inward along said first folding guide to describe a generally inverted V-sectional shape, and a second folding guide along which said body fluid absorbent panel can be folded so as to describe a generally V-sectional shape, said second folding guide lying toward said rear waist region from said first folding guide and extending in parallel to said first folding guide.
