ABSTRACT:
A method for manufacturing a potassium niobate deposited body includes: forming a buffer layer above a substrate composed of an R-plane sapphire substrate; forming above the buffer layer a potassium niobate layer or a potassium niobate solid solution layer that epitaxially grows in a (100) orientation in a pseudo cubic system expression; and forming an electrode layer above the potassium niobate layer or the potassium niobate solid solution layer, wherein a (100) plane of the potassium niobate layer or the potassium niobate solid solution layer is formed to tilt with a [11-20] direction vector as a rotation axis with respect to an R-plane (1-102) of the R-plane sapphire substrate.
