Kind Code:
A1
Abstract:
[Problem] To provide a dielectric composition with high voltage resistance and good reliability, and an electronic component using said dielectric composition. [Solution] This dielectric composition is characterized in that the main component is a tungsten bronze type composite oxide represented by the chemical formula (Sr1.00-(s+t)BasCat)6.00-xRx(Ti1.00-(a+d)ZraSid)x+2.00(Nb1.00-bTab)8.00-xO30.00; R is at least one element selected from Y, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu; s, t, x, a, b and d satisfy 0 ≦ s ≦ 1.00, 0 ≦ t ≦ 1.00, 0 ≦ s+t ≦ 1.00, 0 ≦ x ≦ 3.00, 0.01 ≦ a ≦ 0.98, 0 ≦ b ≦ 1.00, 0.02 ≦ d ≦ 0.15 and 0.03 ≦ a+d ≦ 1.00; and the composition contains 0.10-20.00 mols of at least one element selected from Mn, Mg, Co, V, W, Mo, Li, B and Al as a secondary component per 100 mols of the main component.
