摘要: There is provided a piezoelectric ceramic having a wider operating temperature range, being capable of obtaining a larger amount of displacement, being easily sintered, and being superior in terms of low emission, environment and ecology. A piezoelectric substrate (1) includes (1−m−n){(Na1-x-yKxLiy)(Nb1-zTaz)O3}+m{(M1)ZrO3}+n{M2(Nb1-wTaw)2O6} as a main component. M1 and M2 each represent an alkaline-earth metal element, and the values of x, y, m and n are preferably within a range of 0.1≦x≦0.9, 0≦y≦0.1, 0
