This invention intends to provide a method for inspecting an inner state of an object by determining whether or not any foreign matter is generated inside the object material without being affected by any outside state of the object. This method comprises irradiating waveform of ultrasonic wave to an object whose inner state is desired to be inspected from outside, extracting waveform of a reflected wave traveling inside the object, detecting a difference of acoustic impedance of the foreign matter from the waveform of the reflected wave by extracting a deflection of the waveform and detecting for presence/absence of the foreign matter inside the object or presence/absence of the foreign matter and a quantity of the foreign matter.
