A dielectric composition is provided. The dielectric composition includes: a main component made of: a first complex oxide expressed by a chemical formula {K(Ba1-xSrx)2Nb5O15}; and a second complex oxide expressed by a chemical formula that differs the chemical formula of the first complex oxide. The second complex oxide is a complex oxide expressed by one of chemical formulae: {(Ca1-ySry)(Zr1-zTiz)O3}; {Ba(Ti1-uZru)O3}; {(Ca1-vSrv)TiSiO5}; and {(Ba1-wRe2w/3)Nb2O6}, x satisfies 0.35≤x≤0.75, and a satisfies 0.25≤a≤0.75 when a molar ratio between the first and second complex oxides is defined by a:b in an order and a+b=1.00. |
