Zusammenfassung:	To provide a determination method of quality of a coil wire that can non-destructively determine the quality of a bent portion of the coil wire.SOLUTION: In a determination method of quality of a coil wire according to the present disclosure, when an amount of change in a current or resistance value after bending a bend portion 10a of a coil wire 10 relative to the current or resistance value before bending the bend portion 10a is within a predetermined range, the coil wire 10 is determined to be a good product. Therefore, the quality of the bend portion of the coil wire can be determined non-destructively.SELECTED DRAWING: Figure 1 【課題】コイル線の曲げ部分の良否を非破壊で判定することができるコイル線の良品判定方法を提供する。【解決手段】本開示に係るコイル線の良品判定方法は、コイル線１０の曲げ部分１０ａの曲げ加工前における電流値又は抵抗値に対する、曲げ部分１０ａの曲げ加工後における電流値又は抵抗値の変化量が所定の範囲内である場合、コイル線１０が良品であると判定する。そのため、コイル線の曲げ部分の良否を非破壊で判定することができる。【選択図】図１
