Abstract:
A composite multilayer ceramic electronic part comprising a laminate comprising:a high dielectric-constant layer comprising a high dielectric-constant material comprising (a) a xBaO-yTiO2-zReO3/2 dielectric in which x, y and z are % by mole and satisfy the following conditions: 8&lE;x&lE;18, 52.5&lE;y&lE;65, 20&lE;z&lE;40 and x+y+z=100, and Re is a rare earth element, and (b) a first glass composition, wherein the high dielectric-constant layer has a relative dielectric constant &egr;r of equal to or more than about 20; and at least one low dielectric-constant layer comprising a low dielectric-constant material comprising a composite of a ceramic and a second glass composition, wherein the low dielectric-constant layer has a relative dielectric constant &egr;r of less than or equal to about 10.
