摘要： The present invention has a configuration such that a plurality of leg portion elastic members are arranged around the respective leg openings of a disposable diaper so that the respective leg portion elastic members are not connected or cross each other in a crotch portion, the minimum width of an absorbent article body at the crotch portion is within the range of from 250 to 350 mm, and the opposite side edges in the width direction of the absorbent article body in the crotch portion bend towards the external surface of the diaper, when worn. As a result, the ability for absorbing a large amount of body waste can be easily ensured, and the performance of preventing leakage from the crotch portion can be easily improved.
