A ceramic material has a perovskite structure and is represented by formula of (1−x)ABO3-xYZO3. In the formula,“x”is a real number that is greater than 0 and is less than 1 each of“A,”“B,”“Y,”and“Z”is one or more kinds selected from a plurality of metal ions M other than a Pb ion and alkali metal ions,“A”is bivalent,“B”is tetravalent,“Y”is trivalent or combination of trivalent metal ions, and“Z”is bivalent and/or trivalent metal ions, or a bivalent and/or pentavalent metal ions.
