Claim:
1. A piezoelectric material, comprising: a perovskite type metal oxide having the following general formula (1); an Mn content; and an Mg content, wherein b is a number of moles of the Mn content on a metal basis per mole of the perovskite type metal oxide, b is in the range of 0.0048≦b≦0.0400, and the Mg content on a metal basis per 100 parts by weight of the perovskite type metal oxide is 0.100 parts by weight or less, except 0 parts by weight wherein x is in the range of 0.050≦x≦0.200, y is in the range of 0.010≦y≦0.040, and z is in the range of 0≦z≦0.040, provided that x≧0.375(y+z)+0.050, and a is in the range of 0.9925+b≦a≦1.0025+b, provided that b is in the range of 0.0048≦b≦0.0400.
