PROBLEM TO BE SOLVED: To obtain a polyurethane elastic fiber containing inorganic particles, which reduces abrasion of a metal part occurring in the metal part used during processing when post processing is carried out using the polyurethane elastic fiber. SOLUTION: The polyurethane elastic fiber contains≥0.01 wt.% of the inorganic particles having 0.05-5μm average particle diameter based on the polyurethane elastic fiber and 0.1-5 wt.% of spherical crosslinked organic polymer particles having an average particle diameter equal to or larger than that of the inorganic particles.
