Abstract: An object of the present invention is to provide a polyolefin fiber, particularly a core-sheath composite polypropylene fiber which is possible to be easily deformed corresponding to a stress applied from a direction perpendicular to a fiber axis, to be less fibrillated, and to have an excellent knot strength. The problem of the present invention is solved by providing the polyolefin fiber having a compressive strength of 30 to 51 MPa calculated by the following formula 1 when compressed and deformed by 30% with respect to a fiber diameter in a direction perpendicular to the fiber axis in each single fiber.
