Claim 1
Independent Claim
115 words
A cantilever type probe comprised of a cantilever-shaped displacement element and a tip which displacement element has a first electrode layer, first piezoelectric material film and a second piezoelectric material film which films are laminated on respective sides of the first electrode layer, and a second electrode layer and third electrode layer which layer are laminated on respective 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 are more protruded out than each end of the second and third electrode layers does.
Claim 2
Dependent Claim
38 words
