PROBLEM TO BE SOLVED: To provide a hardening quality inspection device and a hardening quality inspection method capable of improving the inspection accuracy of the hardening quality of an inspection object by correcting a measurement value having variations due to a material charge in nondestructive inspection.SOLUTION: This quality inspection device includes: a power source 2; voltage measurement means 11 for measuring a voltage generated by an inspection object 1 applied with the current by the power source 2; and quality measurement means 12 for measuring a hardening quality of the inspection object 1 from the voltage measured by the voltage measurement means 11. The quality measurement means 12 includes: a previous processing value storage part 15 for storing the measurement value by the voltage measurement means 11 before the hardening processing of the inspection object 1; a post-processing value storage part 16 for storing the measurement value after the hardening processing; and a determination part 17 for determining the hardening quality by comparing each measurement value of before and after the hardening processing stored respectively. |
