Abstract
A disposable absorbent article, having a front-back direction that is perpendicular to a width direction and a thickness direction that extends from a skin contact surface side to a non-skin contact surface side of a wearer, includes: an absorbent constituent; a liquid-permeable topsheet that is disposed on the skin contact surface side of the absorbent constituent; and a leakage-preventing sheet that is disposed on at least one of an outside, in the thickness direction, of the absorbent constituent, and an outside, in the width direction, of the absorbent constituent. The leakage-preventing sheet includes a water repelling layer including a nonwoven fabric. The nonwoven fabric of the water repelling layer includes fiber and has an average fiber diameter of 0.5 to 10 μm. The water repelling layer includes a water repelling section where a group of particles adhere to a surface of the fiber.
