To provide an adhesive state inspecting apparatus and a method for inspecting an adhesive state, even if the adhesive state between two solids into which ultrasonic waves cannot enter, and when a product is large and abnormal section is small.
When the adhesive state between a magnet 1 and a base material 2 is inspected, a coil 3 is provided in the vicinity of the magnet 1; a magnetic field is generated by applying an AC signal from a transceiver 5 to the coil 3; the magnet 1 is vibrated by electromagnetic induction action between a current created by the magnetic field and a magnetic field generated by the magnet 1; fluctuations due to the vibration of the magnet 1 are detected by a laser displacement gauge 4; and the adhesive state, between the magnet 1 and the base material 2, is inspected based on a detection signal.
