Abstract

PURPOSE:To facilitate assembly of a helix type delayed wave circuit by forming a ground metal at least on part of a dielectric post and a filling metallic film on a helix, joining the dielectric post and the helix, and dissolving to remove the ground metallic film. CONSTITUTION:A molybdenum layer 6 is coated on the surface of a ceraminc post 5 by the sputtering method and a copper layer 7 is further coated on the electroplating method. On the other hand, a nickel layer 10 is formed on the surface of a helix 11 by the electroplating method and heated in a hydrogen furnace. Then a helix type delayed wave circuit is obtained by dissolving to remove a copper layer 7' and a molybdenum layer 6' except the waxed area on the surface of the ceramic post 5 using etching solution.
