Abstract: PROBLEM TO BE SOLVED: To stably reload data with little variation in write voltage and achieve high reliability by setting a ferroelectric layer on a surface of a substrate and further a plurality of conductive dots on a surface of the ferroelectric layer. SOLUTION: A ferroelectric layer 13 is set on a surface of an Si semiconductor substrate 121, and a plurality of conductive dots 20 are formed on a surface of the ferroelectric layer 13. An ohmic electrode 11 is provided at a rear face of the substrate 121. For writing, reading of data, a recording medium is scanned by a conductive probe. At this time, the probe is held in touch with the dots 20. In order to write data, a voltage that can reverse a polarization of the layer 13 is applied between the dot 20 scanned by the probe and electrode 11, so that only the ferroelectric body immediately below the above dot 20 is reversed in polarization. In order to read data, a piezoelectric effect of the ferroelectric body, a pyroelectric effect, an electrooptic effect, a current detection when the polarization is reversed, etc., are utilized.  Since the substrate 121 is formed of the semiconductor Si, whether a depletion layer is formed or not in a polarization direction of the layer 13 is rendered distinctive, and recorded data can be held surely.
