Abstract

PURPOSE: In a composite wire material which is constructed in such a way that the metal having a high heat conductivity is covered with a corrosion-resisting metal, the metal having a high heat conductivity on one side of the wire is removed by the fixed length, and by melting the corrosion-resisting metal covering the end surface, the covering is operated, and thus the control electrode for the spark plug having a good heat conductivity is simply manufactured.
