PROBLEM TO BE SOLVED: To provide a non-destructive inspection method which enables the inspection of the surface flaw and internal flaw of an inspection target at the same time and capable of shortening an inspection time. SOLUTION: An inspection area E is provided on the surface of the inspection target 2 being a magnetic body and an inspection medium 8, which is prepared by mixing a magnetic powder used in magnetic powder flaw detection with a contact medium used in ultrasonic flaw detection is applied to the surface of the inspection target 2 from the upper side of the inspection area E to the lower side thereof. In this state, ultrasonic flaw detection is performed on the upper side of the inspection area E and magnetic powder flaw detection is performed in the inspection area E on the lower part side of the region where the ultrasonic flaw detection is performed.
