PROBLEM TO BE SOLVED: To simply and promptly lose the conductivity at a portion to be erased of a conductive pattern that is formed on a base material using a conductive ink.SOLUTION: When a conductive pattern is erased, metal ultrafine particles in a conductive ink at a portion to be erased of the conductive pattern is allowed to be absorbed in fibers by rubbing the portion to be erased using a tip member (nib) 12 made of the fibers at the tip of a holding part 10 of an erasing tool 100, the tip member being wetted with a predetermined liquid. Thus, the conductivity at the portion to be erased of the conductive pattern is lost.SELECTED DRAWING: Figure 1 |
