Abstract:
A piezoelectric element, comprising electrodes and a piezoelectric body formed between the electrodes. The piezoelectric body consists of a perovskite oxide including bismuth, lantern, iron and manganese. The molar ratio of the sum of the bismuth and the lantern to the sum of the iron and the manganese is 0.87 or more and 0.94 or less. The molor ratio of the bismuth to the lantern is 3.57 or more and 4.82 or less.
