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 DEG C to 50 DEG 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)
