摘要：
A dielectric ceramic composition is disclosed which consists principally of barium oxide, titanium oxide, neodymium oxide, samarium oxide and bismuth oxide, which are represented by the following formula xBaO--yTiO.sub.2 --z[(1-a-b)Nd.sub.2 O.sub.3 --aSm.sub.2 O.sub.3 --bBi.sub.2 O.sub.3 ], where 0.10.ltoreq.x.ltoreq.0.20, 0.60.ltoreq.y.ltoreq.0.75, 0.10.ltoreq.z.ltoreq.0.24, x+y+z=1, 0
