PURPOSE:To easily determine the degree of adhesion of respective contact points exposed to central flat parts of cavities of respective electrodes by fitting the respective electrodes into up and down reversely truncated conical cavities of a receiving base and finding continuity on respective lead wires indicated on a continuity inspecting instrument. CONSTITUTION:The electrodes 11 and 12 are fitted respectively into the up and down reversely truncated conical cavities 21 and 31 of the receiving base 10. The presence or absence of continuity on all of plural lead wire groups 1b - 4b and 5b - 8b on the respective cavities 21 and 31 is inspected by the continuity inspecting instrument 15. As a result, the degree of adhesion of the respective contact points 1a - 4a and 5a - 8a exposed to the central flat parts 22 and 32 of the cavities 21 and 31 of the respective electrodes 11 and 12, name ly, the quality of the tip shape of the electrodes 11 and 12 can be easily deter mined. Namely, indicating lamps 1c - 8c do not light up on the contact points which are not brought into contact with the electrodes 11 and 12 among the contact points 1a - 8a. By this method, uselessness to shave off excessively the tips of the electrodes 11 and 12 by a cutting tool for repair can be prevented.
