Abstract
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.
