The present invention provides a strong magnetic force and high heat resistance for a magnetic-field forming magnet that applies a magnetic field to a test object to be inspected by an eddy current flaw detection device. A magnetic-field forming magnet for applying a magnetic field to a test object includes a first magnet and a second magnet. The first magnet has a strong magnet force and the second magnet having higher heat resistance than the first magnet is attached to a near end of the first magnet, the end near the test object.
