DIELECTRIC COMPOSITION, DIELECTRIC LAYER, ELECTRONIC COMPONENT AND LAMINATE ELECTRONIC COMPONENT
[Object] To provide a dielectric composition with high voltage resistance and favorable reliability, and an electronic component using the dielectric composition. [Solving Means] A dielectric composition contains, as a main component, a tungsten bronze type composite oxide represented by a chemical formula (Sr 1.00-(s+t) Ba s Ca t ) 6.00-x R x (Ti 1.00-(a+d) Zr a Si d ) x+2.00 (Nb 1.00-b Ta b ) 8.00-x O 30.00 , 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, 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. At least one element selected from Mn, Mg, Co, V, W, Mo, Li, B, and Al are 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.
