A multilayer ceramic capacitor includes dielectric ceramic layers including crystal grains including a perovskite complex oxide including Ba, Ti, at least one rare earth element Re, and at least one of Ca or Zr. An Re/Ti atomic concentration ratio in a grain interior region GI of the crystal grains is GI(Re), an Re/Ti atomic concentration ratio in a grain boundary region GB of the crystal grains is GB(Re), a Ca/Ti atomic concentration ratio in a grain interior region GI of the crystal grains is GI(Ca), a Ca/Ti atomic concentration ratio in a grain boundary region GB of the crystal grains is GB(Ca), an atomic concentration ratio of a total of Ba and Ca to a total of Ti and Zr is (Ba+Ca)/(Ti+Zr), and about 0.074≥GI(Re)≥about 0.005 and about 1.10≥GB(Re)/GI(Re)≥about 0.90, about 0.250≥GI(Ca)≥about 0 and about 1.10≥GB(Ca)/GI(Ca)≥about 0.90, excluding GI(Ca)=0, and about 0.997<(Ba+Ca)/(Ti+Zr)<about 1.030.
