Abstract: There is provided a non-woven fabric of a crimped composite fiber including: a first propylene-based polymer and a second propylene-based polymer, wherein, in the first propylene-based polymer and the second propylene-based polymer, a melting point of the first propylene-based polymer is higher than a melting point of the second propylene-based polymer by 30 ℃ or more, a ratio (second polymer / first polymer) of melt flow rates (MFR: measurement temperature 230 ℃, load 2.16 kg) of the first propylene-based polymer and the second propylene-based polymer is 1.7 or more, and a component ratio represented by a weight ratio of the first propylene-based polymer / the second propylene-based polymer is 50/50 to 10/90.
