PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, AND ELECTRONIC DEVICE
A piezoelectric material that does not contain lead and has excellent piezoelectric constant and mechanical quality factor in a device driving temperature range (-30°C to 50°C) is provided. A piezoelectric material includes a main component containing a perovskite metal oxide represented by following general formula (1), and a first auxiliary component containing Mn, wherein an amount of the contained Mn is 0.002 moles or more and 0.015 moles or less relative to 1 mole of the metal oxide. (Ba 1-y Bi y ) a (Ti 1-x-z Zr x Fe z )O 3 (1) (where 0.010 ¤ x ¤ 0.060, 0.001 ¤ y ¤ 0.015, 0.001 ¤ z ¤ 0.015, 0.950 ¤ y/z ¤ 1.050, and 0.986 ¤ a ¤ 1.020)
