    摘要: A cantilever type probe comprises a cantilever-shaped displacement element and a tip which displacement element has a first electrode layer, a first piezoelectric material film and a second piezoelectric material film which films are laminated on opposite sides of the first electrode layer, and a second electrode layer and a third electrode layer which layer are laminated on outer surfaces of the piezoelectric material films, and which tip is connected with a leader electrode located at a free end of the surface of the displacement element; wherein in the width direction of the cantilever both ends of the first electrode layer protrude outward more than each end of the second and third electrode layers. A scanning tunneling microscope comprises the cantilever type probe, a driving means for displacing the probe, a stage for specimen so as to approach and locate the specimen to the tip, and a potential applying means for applying a bias voltage between the tip and the specimen. An information processing apparatus further comprises a second potential applying means for applying a pulse and bias voltage between the tip and the recording medium; wherein an information is written on the recording medium and an information in the recording medium is read out by electric current flowing between the tip and the recording medium.
