PROBLEM TO BE SOLVED : To provide a multilayer ceramic capacitor capable of sustaining a sufficient insulation resistance even when a dielectric layer is made thin in order to attain a high capacitance.
SOLUTION : The capacitor 10 (multilayer ceramic capacitor) comprises a capacitor element 11 where an internal electrode 12 and a dielectric layer 14 are laid in layers alternately, and an external electrode 15 provided on the end face thereof. In the capacitor element 11, a high resistance layer 24 is provided between the internal electrode 12 and the dielectric layer 14. The high resistance layer 24 contains a ceramic material, at least one element selected from a group of Mn, Cr, Co, Fe, Cu, Ni, Mo and V, and/or a rare earth element.
