A barium titanate piezoelectric ceramic having good piezoelectric properties and mechanical strength and a piezoelectric element that includes the ceramic are provided. A method for making a piezoelectric ceramic includes forming a compact composed of an oxide powder containing barium titanate particles, sintering the compact, and decreasing the temperature of the compact after the sintering. The sintering includes (A) increasing the temperature of the compact to a first temperature within a temperature range of a shrinking process of the compact; (B) increasing the temperature of the compact to a second temperature within a temperature range of a liquid phase sintering process of the compact after (A); (C) decreasing the temperature of the compact to a third temperature within the temperature range of the shrinking process of the compact after (B); and (D) retaining the third temperature after (C).
