PROBLEM TO BE SOLVED: To solve such a problem that macromolecular nonwoven fabric having the crimps that are given in the conventional manner becomes poor in elasticity and recoverability, when its bulk density becomes low. SOLUTION: The nonwoven fabric includes two or more of macromolecular coils having different average coil diameters in which at least one macromolecular coil having a diameter double or more of that of the smallest coil are included additionally.
