Abstract
The present invention relates to a tape material for manufacturing an ignition plug electrode, the tape material being a member for forming an electrode chip, in which a base metal layer and a precious metal layer are cladded, on a bonded region set on an electrode base material of an ignition plug, the member is in the form of a long tape in which the base metal layer being in contact with the bonded region is cladded with the precious metal layer being in contact with the base metal layer, the base metal layer has a width substantially equal to one of the longitudinal width, lateral width and diameter of the bonded region. According to the present invention, bonding between a precious metal chip and a substrate can be reliably maintained to prolong the life of an ignition plug. Accordingly, precious metals can be efficiently used to save resources.
