Abstract
A method for forming a ferroelectric spontaneous polarization reversal in a desired region of a ferroelectric substrate, wherein thickness of the ferroelectric substrate in the desired region A of the ferroelectric substrate is thinner than in a region B outside the desired region of the substrate, comprising the step of applying a given voltage into the ferroelectric substrate by a liquid electrode method to thereby form a ferroelectric spontaneous polarization reversal in the desired region of the ferroelectric substrate.
