ABSTRACT:
A ceramics sintered compact is provided in which a relative dielectric constant and an electromechanical coupling coefficient are improved in superior balance and which shows a relatively high piezoelectric coefficient. A ceramics sintered compact having a perovskite structure is provided in which a (002)/(200) ratio by X-ray diffraction after polarization is applied is 1.0 or greater.
