Patented recently is a body fluid absorbing article. The article is improved in the spot absorptive and in the diffusivity in an absorbent and in the characteristics of a body fluid migration to the absorbent. The body fluid absorbing article is comprised of an absorbent sandwiched between a body fluid permeable surface member and a body fluid impermeable back member. The absorbent includes an upper layer and a lower layer sequentially from the side of the body fluid permeable surface member. The lower layer has a higher density than that of the upper layer.
