摘要： To provide a surface property inspection device and surface property inspection method with which the surface treatment condition of treated material such as steel subjected to such surface treatments as shot-peening treatment or heat treatment, nitriding, and the like can be non-destructively and precisely inspected, and which offers a high degree of general purpose application. A surface property inspection device 1 includes a AC power supply 10, an AC bridge circuit 20, and a judgment device 30, and the AC bridge circuit 20 has a variable resistor 21 with a variable split ratio ƒﾁ, a benchmark detector 22, and an inspection detector 23. In variable resistor setting step S1, the split ratio ƒﾁ of a variable resistor 21 is adjusted and set so that the output from the AC bridge circuit 20 is increased; after setting a frequency at which the output from the AC bridge circuit 20 is maximized using a frequency setting step S2, in pass/fail judgment step S4, a benchmark sample S is brought into contact with the benchmark detector 22, the sample under inspection M is brought into contact with the inspection detector 23, and the output from the LPF 33 and the threshold value set in the threshold value setting step S3 are compared and a pass/fail judgment is made of the surface condition of the sample under inspection M.
