PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, MANUFACTURING METHOD THEREOF, AND ELECTRONIC DEVICE
PROBLEM TO BE SOLVED: To provide a piezoelectric material which does not contain lead and has good and stable piezoelectric characteristics within practical temperature range of a device.SOLUTION: The solution means to solve above-mentioned problems is a piezoelectric material which contains a main component containing perovskite metal oxide represented by a following general formula (1)(Ba(TiZr)O(1)(0.020≤x≤0.130, 0.996≤a≤1.030 in the formula); a first accessory component containing Mn; and a second accessory component containing electric charge-disproportionated trivalent and pentavalent Bi. A content of Mn is equal to or more than 0.0020 mole and equal to or less than 0.0150 mole based on 1 mole of the metal oxide, and a content of Bi is equal to or more than 0.0004 mole and equal to or less than 0.0085 mole based on 1 mole of the metal oxide.
