PROBLEM TO BE SOLVED : To provide a piezoelectric ceramic electronic component such as a laminate piezoelectric actuator capable of co-sintering with Ni by improving sinterability under a reduction atmosphere, and a method of manufacturing the same. SOLUTION : A piezoelectric ceramic composition is represented by the general formula [100{(1-x)(K1-a-bNaaLib)(Nb1-cTac)O3-xM2M4O3}+αMn+βM4}(0.005≤x≤0.1, 0≤a≤0.9, 0≤b≤0.1, 0≤a+b≤0.9, 0≤c≤0.3, 2≤α≤15 and 0.1≤β≤5.0) and an internal electrode 3 contains Ni as a main component. A piezoelectric ceramic element 1 is obtained by co-sintering the internal electrode 3 and a piezoelectric ceramic layer comprising the piezoelectric ceramic composition under a reduction atmosphere.
