Summary:[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 Zr a ) 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, and b satisfy 0.50 ‰¤ s ‰¤ 1.00, 0 ‰¤ t ‰¤ 0.30, 0.50 ‰¤ s + t ‰¤ 1.00, 1.50 < x ‰¤ 3.00, 0.20 ‰¤ a ‰¤ 1.00, and 0 ‰¤ b ‰¤ 1.00. At least one selected from Mn, Mg, Co, V, W, Mo, Si, Li, B, and Al is 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.
