Abstract:
1. A multi-layer ceramic capacitor having a substantially hexahedral laminate in which dielectric ceramic layers and internal electrode layers are laminated alternately and the internal electrode layers are formed so as to be exposed to end faces opposed to each other alternately, and a pair of external electrodes which are formed at the end faces where the internal electrodes of the laminate are exposed and electrically connected with the internal electrode layers, wherein the internal electrode layer is formed of metal particles comprising Ni, and an arithmetic mean particle diameter of the metal particles is smaller than the thickness of the internal electrode layer, the arithmetic mean particle diameter being determined based on the particle diameter in the direction parallel with the plane direction of the internal electrode layer, wherein the internal electrode layer comprises a conductive metal layer obtained by heat treating a conductive paste in a reducing firing atmosphere having an oxygen partial pressure from about 10 −14 to 10 −18 atm, the conductive paste comprising Ni metal particles coated with a metal or a metal oxide comprising one or more of Mn, Co, Fe, Cu, Nb, Ba, Ca, Sr, Ti, Zn, V, and a rare earth metal.
