A disposable diaper capable of being put on from either the front or the back of a wearer. The ratio of the minimum width W 1 of the crotch section to the whole width W 2 of the longitudinal end section having the fastening tapes is from 0.30 to 0.75. The minimum width W 1 is in the area extending from the centerline across the diaper that divides the diaper length in two equal halves toward both the longitudinal end sections thereof by ±10% of the total length of the diaper. The area ratio S 1 /S 2 is from 0.45 to 0.60, where S 1 is the area of each region surrounded by an imaginary straight line L 1 , an imaginary straight line L 2 , and each arched side edge of the crotch section, and S 2 is the area of each region surrounded by the line L 1 , the line L 2 , and an imaginary straight line L 3.
