Also, since the surface area is large, flat cables provide such merits as being high in heat radiation and are thus high in performance as wiring.
  • a so-called piercing contact is used such that a piercing member equipped by the contact is pierced through a belt-like conductor.
  • a piercing contact is convenient since an electrical connectionwith a flat cable is achievedbypiercing the piercing member through a belt-like conductor and the electrical connection can thus be made readily.
