To produce a nonwoven fabric comprising a conjugated fiber comprising a plurality of resins which are different in thermal shrinkage and form a phase separation structure. In the nonwoven fabric, the conjugated fibers are arranged in a direction approximately parallel to a surface direction of the nonwoven fabric and crimped. In addition, the conjugated fibers have an average curvature radius of fiber crimp of 20 to 200 µm and the crimps are distributed approximately uniformly in a thickness direction of the nonwoven fabric. The nonwoven fabric is substantially free from an adhesive agent. In the nonwoven fabric, each fiber is substantially not melt-bonded to another. The conjugated fiber may comprise a polyalkylene arylate-series resin and a modified polyalkylene arylate-series resin and have a side-by-side or eccentric sheath-core form. Since the bimetal form conjugated fibers having specific crimps are appropriately entangled with each other, the nonwoven fabric has a high stretchability and is easily torn by hand, without using scissors. The nonwoven fabric is suitable for a tape such as a bandage or a supporter.
