PROBLEM TO BE SOLVED: To provide a device for manufacturing a polling reverse structure that makes it possible to easily monitor a polling reverse state even when a metal electrode is used. SOLUTION: Through the device for manufacturing the polling reverse structure that manufactures the pol reverse structure in designated pattern by arranging electrode patterns 2 and 3 on two opposite surfaces of a dielectric substrate 1 which is unipolarized and has nonlinear effect and applying an electric field from a high-voltage power source 6 to the dielectric substrate 1, only a component having changed in polarizing direction is observed with a high contrast by irradiating one surface of the dielectric substrate with light in a designated polarized state through a polarizer 9 and a polarization beam splitter 10, separating a reflected light component in a different polarized state from the irradiation light from the polarizer 9 by the polarization beam splitter 10 and polarizer 11 from reflected light from the one surface side of the dielectric substrate 1, and receiving it by a photodetection section 13.
