A non-destructive sectional shape inspecting apparatus and method. An object to be inspected is internally and/or externally filled with a material capable of reradiating a nuclear magnetic resonance signal, whereon high frequency pulses and gradient magnetic fields are applied to obtain a nuclear magnetic resonance signal which is processed into an image signal. A portion of the image signals where no nuclear magnetic resonance signal makes appearance is extracted to be utilized for plotting the sectional shape of the object under test.
