Abstract

Disclosed is an absorbent article including: a liquid permeable surface member; a backing sheet; and an absorbent layer interposed between the surface member and the backing sheet. The surface member includes an upper layer located at a liquid-receiving side surface and a lower layer located adjacent to the absorbent layer. The upper layer is formed of first continuous filaments. The lower layer is formed of second continuous filaments. The first and second continuous filaments individually extend over the entire length of the surface member. Hydrophilicity of the lower layer is higher than that of the upper layer.
