Abstract:
A piezoelectric element comprises a piezoelectric member made of a complex oxide and an electrode which contains platinum. The complex oxide contains potassium sodium niobate and bismuth ferrate. The molar ratio of the bismuth ferrate to the sum of the potassium sodium niobate and the bismuth ferrate is in the range of 3% to 10%. And the molar ratio of the sum of potassium and sodium to niobium is in the range of 103% to 115%.
