Abstract
A micro-displacement element comprises a unimorph cantilever having a piezoelectric thin film, a pair of electrodes between which the piezoelectric thin film is sandwiched, and an elastic thin film. One end of the cantilever is supported by a support, and the other end thereof is provided with a probe. The micro-displacement element can be used particularly as an array of plural elements, for an information processing apparatus in which the element faces to a recording medium such that an information recording pulse voltage or an information reproducing bias voltage can be applied to between the probe and the recording medium.
