<P>PROBLEM TO BE SOLVED: To provide a glass ceramic multi-layer wiring board with a built-in capacitor for suppressing the inter-diffusion of components in a dielectric layer configuring a capacitor part and components in an insulating layer or glass components in an electrode layer, and for preventing the deterioration of the capacity of a capacitor part formed in the glass cermaic multi-layer wiring substrate, and for suppressing the variation. <P>SOLUTION: A glass ceramic multi-layer wiring board with a build-in capacitor is formed with a capacitor part 14 constituted of a dielectric layer 12 with barium titanate as main components and electrode layers 13a and 13b constituted of the sintered pair of metallic powder and dielectric diffusion preventing layers 15a and 15b and metallize diffusion preventing layers 16a and 16b successively laminated on the upper and lower faces of the capacitor 14, in an insulating substrate constituted of a glass ceramic sintered body containing glass and filler. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
