PURPOSE:To improve the productivity and breakdown strength by a method wherein, after a dielectric paste is discharged and formed on a conductor where a thick-film conductor pattern is formed in advance, a conductor paste is coated on a dielectric in such a way that this paste crosses the conductor. CONSTITUTION:A paste 2 whose air bubbles have been removed in advance is filled in a nozzle 1; a pressure is exerted on the dielectric paste 2 from a nozzle discharge opening 6; the nozzle 1 is actuated by an NC data while an interval between a substrate 3 and the nozzle discharge opening 6 is kept constant; the dielectric paste 2 is discharged and formed; after that, an upper-part conductor 5 is formed in the same manner while the upper-part conductor 5 crosses a lower-part conductor 4. Accordingly, a pinhole at a dielectric and a disconnection at a stepped part of the substrate 3 and the dielectric are not caused. If, when an upper-part conductor paste is discharged, a drawing speed on the substrate 3 and on the dielectric is made slower than the drawing speed at a drawing operation of the stepped part, the disconnection of the upper-part conductor 5 at the stepped part is prevented. By this setup, the productivity and breakdown strength are improved. |
