With a disposable diaper (10), a covering sheet (40) is configured to overlap in a non-skin-contact face side (S1) of an absorbent core (40a). A configuration in a site (A) of overlap by the covering sheet (40b) is such that an end part (41E) of an inner side sheet (41) and an outer side sheet (42) are bonded, and an end part (42E) of the outer side sheet (42) and the inner side sheet (41) are bonded, with an adhesive (1). A configuration in a region whereupon the adhesive (1) is coated is such that a non-adhesive region (B), wherein the inner side sheet (41) and the outer side sheet (42) are not bonded, extends in the product longitudinal direction (L). Indicators (600) are disposed within the non-adhesive region (B).
