Abstract
A structure in which a plurality of leads are formed on a base film that are respectively connected to a plurality of terminal portions of a recording head of an ink jet printer by brazing has slits formed among the plurality of leads at this juncture so that gases generated in brazing are discharged from the slits thereby preventing brazing failure due to scattering of molten solder. Further, a slit maybe formed along a center axis of each of the plurality of leads at the juncture so the molten solder flows into the slits. As a result, the connection strength is improved by fillets formed at both sides of the slits. Further, the gases generated in brazing are also evacuated from the open ends of the slits thereby further minimizing brazing failures.
