Summary:3 3 3 A method for manufacturing (Li, Na, K)(Nb, Ta)Otype piezoelectric material having an improved relative dielectric constant and an electric-field-induced strain is provided. The method is a process in which a formed body of powder particles constituted of a composition of (Li, Na, K)(Nb, Ta)Ois fired to produce the (Li, Na, K)(Nb, Ta)Otype piezoelectric material, and a constant temperature is kept in a range of 850 to 1000° C. for a constant time before heating to a firing temperature.
