PURPOSE:To provide a manufacture of a band material for electric contact by which the total height of the contact can be lowered, and an inexpensive spring material can be used, and further the contact band material can be attached to the spring band material stably. CONSTITUTION:Single-head contact band materials 11, which have fins of base materials integrally, at both sides of a lower part, or both-head contact band materials, which have fins of base materials integrally, at both sides of a middle part, are made, and next, the side end face of the fin on one side of this single- head contact band material 11 or both-head contact is junctioned with the end face on one side of a spring band material 12 by beam welding so as to get a band material for electric contact of single-head contact or both-head contact. |
