Abstract
This invention is a method for manufacturing a rectangular parallelepiped-shaped single crystal containing sodium niobate of a perovskite structure as the main component, and the method includes a process of heating a mixture 1 of bismuth sodium niobate which is formed from particles containing a plurality of crystals represented by General Formula (1): BiNaNbmO(m is an integer of 2 or more) and in which an average value mof the m values is larger than 6 and sodium containing alkali metal halide at 1200° C. or more and 1250° C. or less to obtain a rectangular parallelepiped-shaped single crystal containing sodium niobate as the main component.
