<p>PURPOSE:To obtain an active device which has less secular change in element output. CONSTITUTION:An active device is so constructed that the first electrode 2, the second electrode 3, a powerful dielectric layer and the third electrode 5 are provided in sequence on an insulation board 1 formed of a glass substrate. An active layer is the powerful dielectric layer 4 in a region where it is sandwiched between the first and third electrodes 2, 5. The first electrode is made of material capable to adhere to the powerful dielectric layer 4. It is thus possible to prevent the separation of the powerful dielectric layer 4 from the first electrode 2 and lessen a secular change in element output.</p> |
