Patent ID: 7220691

Claim:
A dielectric ceramic composition comprising: a main component including barium titanate; a first subcomponent including a magnesium oxide; a second subcomponent including a yttrium oxide; a third subcomponent including a vanadium oxide; and a glass component including a silicon oxide as the main component; wherein rates of respective subcomponents with respect to 100 moles of barium titanate as the main component are; the first subcomponent: 0.1 to 3 moles, the second subcomponent: 0.01 or more to less than 0.5 mole, the third subcomponent: 0.01 to 0.2 mole, and the glass component: 0.5 to 10 moles; a manganese oxide and a chrome oxide are substantially not included; an average particle diameter of dielectric particles composing said dielectric ceramic composition is 0.35 μm or smaller; wherein Ba/Ti, indicating a mole ratio of Ba and Ti in the barium titanate, is in a range of 1.011 to 1.030; and wherein the glass component is expressed by a chemical formula M x SiO 3 , wherein “M” includes at least one of Ba, Ca, Sr, Li and B and “x” is in a range of ⅔ to 2.
