Claim:
1. A piezoelectric material comprising: a main component containing a perovskite-type metal oxide that can be expressed by the following general formula (1); a first subcomponent containing Mn; a second subcomponent containing Li; and a third subcomponent containing Bi, wherein the content of Mn on a metal basis is not less than 0.04 parts by weight and is not greater than 0.36 parts by weight when the metal oxide is 100 parts by weight, content α of Li on a metal basis is not less than 0.0013 parts by weight and is not greater than 0.0280 parts by weight when the metal oxide is 100 parts by weight, and content β of Bi on a metal basis is not less than 0.042 parts by weight and is not greater than 0.850 parts by weight when the metal oxide is 100 parts by weight (in the general formula (1), 0.09≦x≦0.30, 0.074≦y≦0.085, 0≦z≦0.02, and 0.986≦a≦1.02).
