A nonwoven fabric, including fibers, in which the fibers have an elongational viscosity, as measured under conditions at an elongational strain rate of 2.5&#xd7;10(1/s) and a temperature of 160&#xb0; C., of from 430 Pa&#xb7;s to 1200 Pa&#xb7;s, and a ratio of the elongational viscosity (Pa&#xb7;s) to a shear viscosity (Pa&#xb7;s) of the fiber, as measured under conditions at a shear strain rate of 2.5&#xd7;10(1/s) and a temperature of 160&#xb0; C., is from 35 to 65.
