Abstract: Provided is a crimped fiber constituted of the following first component and second component, wherein the first component is a propylene-based resin composition containing a propylene-based polymer (1-A) in which a melting point (Tm-D) obtained under a specified condition exceeds 120° C. and a propylene-based polymer (1-B) satisfying the conditions that (a) a weight average molecular weight (Mw) is 10,000 to 200,000, (b) a molecular weight distribution (Mw/Mn) is less than 4.0, and (c) a melting point (Tm-D) obtained under a specified condition is 0 to 120° C.; and the second component is a propylene-based polymer (2) in which a melt flow rate (MFR) under the foregoing measurement condition is 1 g/10 min or more and 2,000 g/10 min or less, and a melting point (Tm-D) observed under the foregoing measurement condition by using a differential scanning calorimeter (DSC) exceeds 120° C., or a propylene-based resin composition containing the propylene-based polymer (2).
