PURPOSE:To attain a deflection having a large angle by forming perovskite or tungsten bronze type polycrystal as a prism to form an electrode for generating an electric field rectangular to a light transmission direction. CONSTITUTION:The rays of light from a light source 7 are made incident upon a prism-like perovskite type polycrystalline light deflecting element 1, and while changing voltage to be applied, the deflection angle is measured. Consequently, the rays of light can be oscillated by >=1 deg. in case of vertical polarization and an optional deflection angle can be selected because the deflection angle is large.
