摘要： An insulating film is formed on a first principal surface of the substrate. A periodic structure formation zone corresponding to a periodic structure formation region to be formed in the substrate, a plurality of polarization inversion zones corresponding to polarization inversion regions to be formed in a periodic arrangement in the periodic structure formation region, and a connection zone corresponding to a connection region to connect the plurality of polarization inversion regions, are set on the insulating film. The portions of the insulating film in the polarization inversion zones and the connection zone are removed, forming an insulating film pattern which exposes portions of the first principal surface of the substrate. A high voltage is applied, through an electrolytic solution, across the portions of the first principal surface exposed out of the insulating film pattern and the second principal surface of the substrate, to cause inversion of the polarization direction in the polarization inversion regions.
