ABSTRACT:
A monolithic ceramic capacitor has laminated plural dielectric ceramic layers, internal electrodes disposed between dielectric ceramic layers, and external electrodes formed at edge surfaces of the dielectric ceramic layers such that they are connected to alternate internal electrodes, wherein the dielectric ceramic layers are composed of a material comprising a principal component shown by the formula: (1-.alpha.-.beta.-.gamma.){BaO}.sub.m.TiO.sub.2 +.alpha.M.sub.2 O.sub.3 +.beta.Re.sub.2 O.sub.3 +.gamma.(Mn.sub.1-x-y Ni.sub.x Co.sub.y)O (wherein M.sub.2 O.sub.3 is at least one kind of Sc.sub.2 O.sub.3 and Y.sub.2 O.sub.3 ; Re.sub.2 O.sub.3 is at least one kind of Sm.sub.2 O.sub.3 and Eu.sub.2 O.sub.3 ; 0.0025.ltoreq..alpha.+.beta..ltoreq.0.025, 0<.beta..ltoreq.0.0075, 0.0025.ltoreq..gamma..ltoreq.0.05, .gamma./(.alpha.+.beta.).ltoreq.4, 0.ltoreq.x<1.0, 0.ltoreq.y<1.0, 0.ltoreq.x+y.ltoreq.1.0, and 1.000<m.ltoreq.1,035), and containing definite amounts of MgO and SiO.sub.2 as side components.
