Abstract:
A multilayer ceramic capacitor that includes outer electrodes and a multilayer body having stacked inner electrode layers and dielectric layers. The dielectric layers in an effective section contain, relative to 100 parts by mole of Ti, 0.7 to 1.2 parts by mole of Si, 0.9 to 1.1 parts by mole of Dy, 0.24 to 0.34 parts by mole of Mg, 0.17 to 0.23 parts by mole of Al, 0.09 to 0.11 parts by mole of Mn, and 0.04 to 0.06 parts by mole of V. The dielectric layers have a Ba/Ti molar ratio of 1.0073 to 1.0083.
