A high frequency dielectric ceramic composition includes : as a major component a composition which contains a rare earth element (Re), Al, Sr, and Ti as metal elements and has a composition formula expressed by a molar ratio of aRe2O3-bAl2O3-cSrO-dTiO2 in which a, b, c, and d satisfy the following formula; 0.113≦a≦0.172, 0.111≦b≦0.171, 0.322≦c≦0.388, 0.323≦d≦0.396, and a+b+c+d=1.000; and 0.01 to 2 parts by weight on a Fe2O3 conversion basis of Fe as an element, based on 100 parts by weight of the major component.
