Disclosed is: a body fluid treatment article wherein twisting while being worn can be inhibited and a method for manufacturing the same. The panty liner (1) comprises: inner and outer surface sheets (2, 3) a fluid-absorption interlining (4) located between the inner and outer surface sheets (2, 3) and a leakproof sheet (5) with which the outer surface sheet (3) is covered. A fiber nonwoven fabric containing thermoplastic synthetic resin is used as the inner and outer surface sheets (2, 3), and fluff pulp is used as the interlining (4). On the inner surface sheet (2) are formed a plurality of compressed grooves (7) toward the outer surface sheet (3) in a manner that the compressed grooves (7) form a grid pattern by extending so as to cross one another respectively in the lengthwise direction (Y) and the crosswise direction (X). The compressed grooves (7) comprise a first portion formed from the inner surface sheet (2) toward the interlining (4) and second portions each provided with a bottom and formed from the lower part of the first portion toward the outer surface sheet (3) in such a manner that the interval between both of the lateral sides is reduced gradually. At the bottoms of the second portions, at least parts of the fibers forming the inner surface sheet (2) and the fibers forming the outer surface sheet (3) are in contact with each other and welded.
