PURPOSE:To prevent the cavitation in electrode parts without using any noble metals by sticking a material prepd. by mixing and dispersing powders of glass and metal to a conduit formed of enamel then drying and calcining the same. CONSTITUTION:A pair of electrode installing holes 5, 5 are formed to a conduit 4 in the positions where electrodes are to be installed by facing the same each other. Paste 8 for forming electrodes is stuck on the end surface of a prepared stamp part 6, and is stuck on the inside part of the holes 5 and the inside surface of the conduit 4 around said holes from the inside of the pipe 4, whereby electrode films 8a are formed. The paste 8 is stuck on the inside parts and outside circumferential parts of the holes 5 from the outside of the conduit 4 as well and is brought into contact with the paste from the inside surface, whereby electrode terminal parts 9 are formed. After the paste parts for electrodes are dried to allow solvents to evaporate, said parts are calcined. As a result, the glass of the paste melts and enters among the powder particles of the metal in the paste, thereby providing the effect of joining the powder particles of the metals to each other and forming the electrodes. |
