Abstract
A microwave ceramic composition containing as main components substances expressed by a composition formula of x.BaO - y TiO.sub.2 - z.Nd.sub.2 O.sub.3 (where 0.05<=x<=0.25, 0.60<=y<=0.85, and 0.05<=z<=0.225) when their molar fractions are taken as x, y and z (x+y+z=1) and containing as a subcomponent one type selected from the group consisting of In.sub.2 O.sub.3, Bi.sub.2 O.sub.5, GeO.sub.2 and V.sub.2 O.sub.5.
