Provided is a piezoelectric material excellent in piezoelectricity. The piezoelectric material includes a perovskite-type complex oxide represented by the following General Formula (1). A(Zn x Ti (1-x) ) y M (1-y) O 3 (1) wherein A represents at least one kind of element containing at least a Bi element and selected from a trivalent metal element; M represents at least one kind of element of Fe, Al, Sc, Mn, Y, Ga, and Yb; x represents a numerical value satisfying 0.4≦x≦0.6; and y represents a numerical value satisfying 0.1≦y≦0.9.
First claim
Opening claim text (preview).
What is claimed is: 1. A metal oxide comprising a perovskite-type oxide represented by general formula (1): A(Zn x Ti (1-x) ) y M (1-y) O 3 (1) wherein A is made of only a Bi element; M represents at least one element selected from the group consisting of Fe, Al, Sc, Mn, Y, Ga, and Yb; x represents a numerical value satisfying 0.4≦x≦0.6; and y represents a numerical value satisfying 0.1≦y≦0.9, wherein the metal oxide is a bulk solid. 2. The metal oxide according to claim 1 , wherein M is made of at least one of Fe and Al or both of Fe and Al. 3. The metal oxide according to claim 1 , wherein M contains an Mn element in an amount of 0.1 mol % or more to 5 mol % or less. 4. The metal oxide according to claim 1 , wherein y satisfies 0.2≦y≦0.65. 5. A piezoelectric material comprising the metal oxide according to claim 1 . 6. The metal oxide according to claim 1 , wherein y satisfies 0.35≦y≦0.65.
