PROBLEM TO BE SOLVED: To provide a simpler nondestructive inspection method of a signal wire with a shield. SOLUTION: A reference value V3 used as a sensor output is acquired by measuring a reference signal wire by an eddy current type sensor, and a discrimination upper limit value V6 in consideration of allowable tolerancesΔ1,Δ2 and a discrimination lower limit value V7 are set on the reference value, and it is determined whether a measured value Vact of the signal wire which is a diagnosis object satisfies the inequality: V7≤Vact≤V6 or not, to thereby inspect a deteriorated portion of the shield of the signal wire with the shield. In addition, this simpler nondestructive inspection method of the signal wire with the shield can be acquired by using the eddy current type sensor. COPYRIGHT: (C)2007,JPO&INPIT
