PURPOSE:To form an electrode having sufficient adhesive strength on a ceramic of a brittle surface state without changing its characteristics by melt spraying metal such as Al on the surfaces of electrically conductive adhesive resins coated and hardened on the surfaces of a ceramic substrate. CONSTITUTION:After the surfaces of a ceramic substrate 3 are finished to prescribed surface roughness, solns. of conductive adhesive resins 4a, 4b such as conductive epoxy are coated on the surfaces thereof. Next, the resins 4a, 4b are set by a heat treatment or the like. Thereafter, Al is melt-sprayed on the surfaces thereof, whereby electrodes 5a, 5b are made. As a result, strong adhesive force is obtained in the same way as that when metal is melt-sprayed on a strong ceramic, and since the resins 4a, 4b are conductive, no influences are given upon the electrical characteristics of the ceramic. |
