Abstract

A piezoelectric material contains a main component containing a perovskite-type metal oxide represented by general formula (1), a first sub-component containing Mn, and a second sub-component containing Bi or Bi and Li. A Mn content relative to 100 parts by weight of the metal oxide is 0.500 parts by weight or less (including 0 parts by weight) in terms of metal, a Bi content relative to 100 parts by weight of the metal oxide is 0.042 parts by weight or more and 0.850 parts by weight or less in terms of metal, and a Li content relative to 100 parts by weight of the metal oxide is 0.028 parts by weight or less (including 0 parts by weight) in terms of metal:(BaCaSn)(TiZr)O(where 0.020≦≦0.200, 0.020≦≦0.200, 0≦≦0.085, 0.986≦α≦1.100)  General formula (1).
