RECOVERY METHOD FOR ELECTRODE

摘要

PROBLEM TO BE SOLVED: To facilitate and ensure the formation of predetermined roughness on the connecting surface of an electrode of a worn electrode plate. SOLUTION: A transfer surface 10a of a transfer plate 10 having a predetermined transfer surface 10s with prescribed roughness is brought into contact, at predetermined pressure, with a plurality of bumps 44B on a contact sheet 44 which is formed on a substrate 44M having a linear expansion coefficient larger than that of the transfer plate 10. Simultaneously, the substrate 44M and the transfer plate 10 are heated to a predetermined temperature to recover the roughness of the connecting surface of the bump 44B at a predetermined level.
