To provide a glass ceramic multilayered wiring board where a capacitor high and uniform in capacity is formed by providing a dielectric layer of barium titanate inside the insulating base body and/or on the surface of the insulating base body.

The glass ceramic multilayered wiring board 1 is composed of the insulating base body 2 formed of a glass ceramic sintered material and the dielectric layer 3 which is equipped with conductor layers 4a and 4b on its top surface and undersurface and provided inside the insulating body 2 and/or on the surface of the insulating body 2. The dielectric layer 3 is formed of a barium titanate powder which is 0.05 to 0.2 μm in average grain diameter and has a pseudo-cubic structure through a gas deposition method.
