Abstract
The ferroelectric substrateof ferroelectric crystals, while being supported by the support platewhich is thicker than the ferroelectric substrate, is integrated with the support plateby letting the junctionmediate between one major surface SA of the ferroelectric substrateand one major surface SB of the support plate, and therefore, it is possible through the flat surface polishing to perform thinning of the ferroelectric substrate, namely, the ferroelectric crystals, and as a result, it is possible to obtain the thin periodically poled structure. By the voltage application method, the domain inverted region is formed in the ferroelectric substratewhich is made thin.
