Claim:
A body fluid absorbent article, which has a body fluid retainable absorbent member having a pair of side portions with side edges disposed under a face sheet and a body fluid permeable absorbent member having a pair of side portions with side edges interposed between said face sheet and said body fluid retainable absorbent member, comprising: said body fluid permeable absorbent member including an assembly of fibers in tows, each fiber of which is a continuous cellulose acetate fiber having a fineness of 1 to 16 denier and a porosity in the permeable absorbent member of 60 to 85%; said body fluid permeable absorbent member disposed only at a zone of said body fluid retainable absorbent member, which is a middle portion in the width direction of said body fluid retainable absorbent member; gutters inwardly formed by embossed regions of high density on said body fluid retainable absorbent member along the longitudinal direction thereof at a portion on an upper surface of a layer thereof in the both side portions with respect to the respective both side edges of said body fluid permeable absorbent member and at the same time not covered with said body fluid permeable absorbent member, and the gutters are not formed on said body fluid retainable absorbent member at a portion located on the upper surface of the layer thereof and covered with said body fluid permeable absorbent member so that after body fluid is diffused through said body fluid permeable absorbent member, the gutters prevent body fluid from diffusing across the gutters towards the side edges of said body fluid retainable absorbent member; said body fluid permeable absorbent member is disposed only at a zone of said body fluid retainable absorbent member, which is a middle portion in the width direction and at the same time, which is an intermediate portion in the longitudinal direction of said body fluid retainable absorbent member; and the gutters are inwardly formed by embossed regions of high density on the body fluid retainable absorbent member along the width direction of said body fluid retainable absorbent member at a portion on the upper surface of the layer thereof in back and front with respect to a back edge and a front edge of said body fluid permeable absorbent member, respectively, and at the same time not covered with said body fluid permeable absorbent member.
