PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, AND ELECTRONIC EQUIPMENT

摘要

A piezoelectric material contains a main component containing a perovskite-type metal oxide having the formula (1); a first auxiliary component composed of Mn; and a second auxiliary component composed of Bi or Bi and Li, wherein the Mn content is 0.04 parts by weight or more and 0.400 parts by weight or less on a metal basis per 100 parts by weight of the metal oxide, the Bi content is 0.042 parts by weight or more and 0.850 parts by weight or less on a metal basis per 100 parts by weight of the metal oxide, and the Li content is 0.028 parts by weight or less (including 0 parts by weight) on a metal basis per 100 parts by weight of the metal oxide.;(Ba1-xCax)a(Ti1-y-zSnyZrz)O3  (1);(wherein 0≦x≦0.080, 0.013≦y≦0.060, 0≦z≦0.040, and 0.986≦a≦1.020.)
