Claim 8:
9. A flexible printed circuit (FPC) connection method of connecting an FPC to a printed circuit board using an FPC connection structure comprising a plurality of strands of FPC conductor patterns coated with an insulating film and a plurality of flat-plate FPC terminals, each flat-plate FPC terminal having a first width and extending from an end portion of a corresponding one of the FPC conductor pattern strands, wherein each flat-plate FPC terminal is adapted to enable spot welding on a substrate terminal unit provided on the printed circuit board, the method comprising:
bonding the plurality of flat-plate FPC terminals extending from the end portions of the plurality of FPC conductor pattern strands to the substrate terminal unit of the printed circuit board by applying a spot resistance welding method such that each of the flat-plate FPC terminals comprises a first bonding portion which is in surface contact on the substrate terminal unit and is spot welded to the substrate terminal unit, wherein the first bonding portion has a second width less than the first width.
