Abstract
A periodic polarization reversal electrode, periodic polarization reversal structure forming method and periodic polarization reversal element. The element includes a plurality of stripe electrode sections with a stripe shape extending in parallel at a gap from each other, arranged in contact with the +Z surface of a ferroelectric crystal substrate; an insulation film arranged over the +Z surface so as to cover the plurality of stripe electrode sections; and an equipotential electrode section which has a portion that opposes at least a part of each of the plurality of stripe electrode sections across the insulation film and is arranged over the insulation film without contacting the ferroelectric crystal substrate or the plurality of stripe electrode sections, wherein an electric field is generated in the area of the ferroelectric crystal substrate directly below the plurality of stripe electrode sections by applying a voltage to the equipotential electrode section.
