<p>A piezoelectric ceramic composition includes a bismuth layer compound, e.g., (Sr 0.9 Nd 0.1 ) Bi 2 Nb 2 O 9 , as a main component containing at least Sr, Bi, and Nb and 2 parts by weight or less (excluding 0 part by weight), preferably 0.04 part by weight to 0.5 part by weight, of Cu in terms of CuO relative to 100 parts by weight of the main component. From the viewpoint of improvement in sinterability, 0.1 part by weight to 2 parts by weight of Mn in terms of MnCO 3 is preferably contained relative to 100 parts by weight of the main component. As a result, it is possible to obtain a piezoelectric ceramic composition causing no deterioration in piezoelectricity even when a rapid temperature change occurs, and a piezoelectric component, such as a piezoelectric actuator or a piezoelectric resonator, manufactured using the piezoelectric ceramic composition.</p> |
