Abstract
A dielectric composition including a tungsten bronze type composite oxide as a main component represented by (Ba1-xSrx)aRbZrcTadO30+0.5e in terms of an atomic ratio. In the dielectric composition, c=(2a+3b−10)−e and d=(20−2a−3b)+e are satisfied. R includes at least one selected from the group consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, and Sc. In the dielectric composition, 0.000≤x≤0.500, 5.100≤a≤5.860, 0.000≤b≤0.100, and −0.150≤e≤0.150 are satisfied.
