ABSTRACT:
It is provided a novel method of producing polarization inversion parts by electric field polling process wherein the polarization inversion part extends to a deeper point from the surface of a substrate. The polarization inversion part is produced by electric field polling process using a comb electrode having a plurality of electrode portions5and a feeding portion1. Each electrode portion5has a base portion6extending from the feeding portion1and a plurality of conductive portions5a, 5band5cseparated from the base portions6, and the conductive portions have an average length “d” of 4 μm or longer and 9 μm or shorter. Alternatively, each electrode portion5has a base portion6extending from the feeding portion1and a plurality of conductive portions5a, 5band5cseparated from the base portion6, and the conductive portion5bat the tip end of the electrode portion has a length “db” smaller than the length “da” of the conductive portion5bnearest to the base portion.
