Zusammenfassung:PURPOSE:To obtain the subject nonwoven fabric having excellent durability and exhibiting anti-inflammatory effect by using a nonwoven fabric containing a specific amount of fibers containing polyolefin polymer exposed to the surface and thermally fixing an allantoin compound to the surface of said polymer. CONSTITUTION:The base material for the objective nonwoven fabric is a nonwoven fabric containing at least 5% of fiber containing a polyolefin polymer exposed to a part or total of the surface of the fiber or a laminated nonwoven fabric having said nonwoven fabric as a surface layer. Solid particles of an allantoin compound are scattered on the surface part of said polyolefin polymer and are thermally fixed at a temperature not lower than the softening point of the polymer and below 245 deg.C. The obtained nonwoven fabric having thermally fixed solid particles of the allantoin compound exhibits anti-inflammatory effect because of the resistance of the solid particles to falling-off or little dissolution of the particles by urination. The nonwoven fabric is extremely suitable as diaper, etc.
