PROBLEM TO BE SOLVED: To provide a wig stopper pin which can fix a wig to self hair and does not react with a metal detector. SOLUTION: In a practical test, a sample 1 and a sample 2 in the evaluations of the spring properties of pins were [○]. Samples 1 to 5 were not detected, but a sample 6 was detected, in the examination of reactivity with a metal detector, wherein five samples in a total weight of 10g are together tested, respectively. Namely, the sample 1 was good in both the evaluations of the pin spring property and the non-reactivity with the metal detector. The chemical components of the sample 1 were≤0.05 mass % of N,≤0.10 mass % of C,≤0.015 mass % of H,≤1.00 mass % of Fe,≤0.25 mass % of O, 3.50 to 4.50 mass % of Al, 20.00 to 23.00 mass % of V, and Ti of Bal.
