Claim:
1. A piezoelectric material comprising: Na, Ba, Nb, Ti, and at least one of Si and B, wherein a ratio “y” of a content (mol) of Nb with respect to a total content (mol) of Nb and Ti is 0.85≦y≦0.95, a ratio “x” of a content (mol) of Na with respect to the total content (mol) of Nb and Ti is 0.80≦x≦0.95, a ratio “b” of a content (mol) of Ba with respect to the total content (mol) of Nb and Ti is 0.05≦b≦0.15, and a total content (part by weight) of Si and B is 0.001 parts by weight or more and 4.000 parts by weight or less with respect to 100 parts by weight of an oxide including Na, Ba, Nb and Ti.
