PROBLEM TO BE SOLVED: To provide a pants type disposable diaper favorably preventing leakage from the circumferences of the legs, while preventing the legs from being tightened excessively and, when putting a diaper on a baby, allowing easy insertion of the baby's legs into leg opening parts and allowing its easy detachment even if the baby is lying. SOLUTION: This pants type disposable diaper 1 is provided with a liquid retainable absorbent body and is formed by detachably joining the both-side edge parts of an abdominal side part A with the both-side edge parts of the back side part B by a mechanical hook-and-loop fastener or the like to form a waist opening part and a pair of leg opening parts. A ratio (L1/L2) of the minimum value L1 of the crotch width to a distance L2 in the diaper longitudinal direction from a point P positioned on an opening edge part 82 of each leg opening part where the crotch width becomes the minimum, to an end point Q in the side of the abdominal side part A of the opening edge part 82 is 1.7-2.2.
