DIELECTRIC CERAMIC COMPOSITION AND CERAMIC CAPACITOR
A dielectric ceramic composition that includes an oxide (I) of A, R, and B, in which the oxide (I) has a tetragonal tungsten bronze type structure; the A contains K and Ba; the R is at least one selected from a group consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, and Sc; the B is at least one selected from a group consisting of Nb and Ta; the B is contained in an amount of 4.75 mol or more and 5.25 mol or less with respect to 2 mol of the A; and the A, R, and B are contained in a total molar fraction of 0.975 or more with respect to all metal elements contained in the dielectric ceramic composition.
