摘要 |
A piezoelectric material that does not contain lead and has excellent and stable piezoelectric properties in a device operating temperature range is provided. The present invention for this purpose is a piezoelectric material including a main component containing a perovskite metal oxide represented by following general formula (1), a first auxiliary component containing Mn, and a second auxiliary component containing Bi charge-disproportionated into trivalent and pentavalent, wherein an amount of the contained Mn is 0.0020 moles or more and 0.0150 moles or less relative to 1 mole of the metal oxide, and an amount of the contained Bi is 0.0004 moles or more and 0.0085 moles or less relative to 1 mole of the metal oxide.;Baa(Ti1-xZrx)O3 (1);(where 0.020≦x≦0.130 and 0.996≦a≦1.030). |
