The present invention addresses the problem of providing a pants-type disposable diaper constructed with a split outer body in which opening at the end parts of the outer body on the crotch side is prevented, while ensuring that an illustration on an illustration sheet can be seen clearly. This problem is resolved by means of a configuration in which: a front-side outer body (12F) and a back-side outer body (12B) include a non-elastic region (A1) in an intermediate part, in the width direction, of a front-back direction region having an absorbent body (56) the non-elastic region (A1) includes an inside sheet layer (12H) and an outside sheet layer (12S) which continue from an elastic region (A2), and unnecessary resilient and elastic members (18) which have been left between the inside sheet layer (12H) and the outside sheet layer (12S) an illustration sheet (25) visible from the outside surface is provided adjacent to and inside the outside sheet layer (12S) in the non-elastic region (A1) the unnecessary resilient and elastic members (18) are not secured to the inside surface of the illustration sheet (25) or the outside surface of the inside sheet layer (12H) and the front-side outer body (12F) and the back-side outer body (12B) include a crotch-side folded-back part (20) which is formed by folding a crotch-side end portion of a sheet material which forms the outside sheet layer (12S) back onto the inside of the inside sheet layer (12H) and securing said sheet material to the inside of the inside sheet layer (12H).La présente invention concerne une couche jetable de type culotte constituée dun corps externe fendu, avec laquelle louverture au niveau des parties dextrémité du corps externe sur le côté dentrejambe est empêchée, tout en garantissant quune illustration sur une feuille dillustration peut être vue clairement. Ces caractéristiques sont obtenues au moyen dune configuration dans laquelle : un corps externe côté avant (12F) et un corps externe côté arrière (1
