What is claimed is: 1 . A dielectric comprising a composite oxide having composition represented by Ce x Al 1-x O k , the composite oxide being amorphous, wherein in the composition, a requirement 0.400≤x<0.900 is satisfied, and k is a value for maintaining electroneutrality of the composite oxide. 2 . The dielectric according to claim 1 , wherein the dielectric includes a sputtered film. 3 . The dielectric according to claim 1 , wherein the dielectric is for a capacitor. 4 . A capacitor comprising: a first electrode; a dielectric disposed on the first electrode; and a second electrode covering at least a portion of the dielectric, wherein the dielectric is the dielectric according to claim 1 . 5 . The capacitor according to claim 4 , wherein at least a portion of the first electrode is a porous portion. 6 . The capacitor according to claim 4 , wherein the first electrode includes a valve metal. 7 . The capacitor according to claim 6 , wherein the valve metal includes at least one selected from the group consisting of aluminum, tantalum, and niobium. 8 . The capacitor according to claim 4 , wherein the second electrode includes at least one selected from the group consisting of aluminum, tantalum, niobium, gold, silver, platinum, and nickel. 9 . The capacitor according to claim 5 , further comprising an electrolyte in contact with the second electrode, wherein the electrolyte fills the porous portion and includes at least one selected from the group consisting of an electrolyte solution, an electrically conductive polymer, and manganese oxide. 10 . An electrical circuit comprising the capacitor according to claim 4 . 11 . A circuit board comprising the capacitor according to claim 4 . 12 . An apparatus comprising the capacitor according to claim 4 .
