摘要：
A dielectric ceramic composition is disclosed which consists essentially of: a main ceramic composition containing barium oxide, titanium oxide, rare earth oxide and bismuth oxide as major components, which composition is represented by xBaO.yTiO.sub.2.z[(1-a)RE.sub.2 O.sub.3.aBi.sub.2 O.sub.3 ] where RE represents at least one rare earth metal, 0.10.ltoreq.x.ltoreq.0.20, 0.60.ltoreq.y.ltoreq.0.75, 0.10.ltoreq.z.ltoreq.0.25, x+y+z=1 and 0
