摘要：

Dielectric ceramic composition comprising a compound shown by a general formula {A1-x(RE)2x/3}y-B2O5+y and has a tungsten bronze-type structure. In the formula, &ldquo;A&rdquo; is at least one selected from a group comprising Ba, Ca, Sr and Mg, &ldquo;B&rdquo; is at least one selected from Nb and Ta, &ldquo;RE&rdquo; is at least one selected from Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, and said &ldquo;x&rdquo; and &ldquo;y&rdquo; satisfies 0<x<1 and y<1.000, respectively. The dielectric ceramic composition further comprises an oxide of at least one selected from V, Mo, Fe, W, Mn and Cr.
