ABSTRACT:
A dielectric material comprising: a composition represented by aBaO.bTiO2.cREO3/2.dBiO3/2, wherein a, b, c and d each independently represent a molar ratio satisfying the following requirements: a+b+c+d=1, 0.09≦a≦0.16, 0.54≦b≦0.62, 0.20≦c≦0.34 and 0≦d≦0.10; and RE represents a rare earth metal; and from 5 to 50 parts by mass, per 100 parts by mass of the composition, of a glass containing a component represented by kBaO.lZnO.mB2O3.nSiO2, wherein k, l, m and n each independently represent a composition percentage satisfying the following requirements: k+l+m+n=100, 25≦k≦55, 5≦1≦30, 15≦m≦35 and 5≦n≦30.
