    摘要: A piezoelectric ceramic composition that acquires excellent piezoelectric properties even when it is fired at a low temperature is offered. The piezoelectric ceramic composition possesses a composition corresponding to a solid solution that contains a first compound having a rhombohedral crystal-based perovskite structure, a second compound having a tetragonal crystal-based perovskite structure, and a third compound. The third compound is a compound oxide containing Bi as a first component element, Fe or Mn as a second component element, and a hexavalent metallic element as a third component element. The hexavalent metallic element is at least one kind selected from W and Mo.
