Abstract
A comb electrode 3 is provided on a first main face 2a and a uniform electrode 4 is provided on a second main face 2b of a substrate made of a ferroelectric single crystal of a single domain, and a voltage is applied on the comb electrode 3 and the uniform electrode 4 to produce domain inversion part. It is laminated, on the substrate, an underlying substrate comprising a main body 5, a first conductive film 6 provided on a first main face 5a and a second conductive film 7 provided on a second main face 5b of the main body 5. The uniform electrode 4 is electrically conducted with the first conductive film 6 and a voltage is applied on the comb electrode 3 and the second conductive film 7 to form a domain inversion part in the substrate 2.
