PIEZOELECTRIC CERAMIC, MANUFACTURING METHOD THEREFOR, AND ELECTRONIC COMPONENT
An object of the present invention is to provide a piezoelectric ceramic which is slightly deformed by firing, a manufacturing method therefor, and an electronic component. There is provided a piezoelectric ceramic 1 including a plurality of crystal grains 2 including a lead zirconate titanate-type crystal containing Zn, and Bi, and crystal grain boundaries 3 existing between a plurality of the crystal grains 2, wherein a plurality of the crystal grains 2 include first crystal grains 2a, and wherein the first crystal grains 2a have a content of at least one element of Zn and Bi present in the inside of the first crystal grains 2a that is smaller than the content of the at least one element present in an area including the crystal grain boundaries 3 that are in contact with the crystal grains 2. The piezoelectric ceramic 1 is slightly deformed by firing and is capable of forming an electronic component which has little warp or deformation even if it is thin.
