    摘要: A non-woven fabric is characterized by including a filament layer in which one or more continuous filaments composed of a polymeric material are spirally collected substantially along a shape obtained by offsetting an ellipse having an elongated major axis in a plane. This non-woven fabric can be obtained by spinning a filament composed of a polymeric material, vibrating the filament, amplifying vibration of the filament, and collecting the filament into an elliptic shape having an elongated major axis so that the filament is arranged in a direction of the major axis.
