    摘要： A dielectric composition with high voltage resistance and favorable reliability, and an electronic component using the dielectric composition. A dielectric composition contains, as a main component, a tungsten bronze type composite oxide represented by a chemical formula (Sr1.00−s−tBasCat)6.00−xRx(Ti1.00−aZra)x+2.00(Nb1.00−bTab)8.00−xO30.00, in which the R is at least one element selected from Y, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, and s, t, x, a, and b satisfy 0.70≤s≤1.00, 0≤t≤0.30, 0.70≤s+t≤1.00, 0≤x≤0.50, 0.10≤a≤1.00, and 0≤b≤1.00. At least one or more elements selected from Mn, Mg, Co, V, W, Mo, Si, Li, B, and Al arc contained as a sub component in 0.10 mol or more and 20.00 mol or less with respect to 100 mol of the main component.

    摘要： A novel ceramic composition having a high relative dielectric constant. A ceramic composition includes a unit cell having at least two crystal structures selected from the group made of a monoclinic crystal, a tetragonal crystal, an orthorhombic crystal, and a rhombohedral crystal, characterized in that when the crystal structures are represented by the symmetry notation according to the Glazer method, namely xn1yn2zn3, n1, n2, and n3 are at least one selected from the group made of + and −, or at least two selected from the group made of 0, +, and −. By using this ceramic composition, a novel ceramic composition having a high relative dielectric constant can be obtained.
