面処理を施している。Conventionally, a flexible plate formed by laminating thin copper plates, or a flexible terminal formed by welding a terminal plate made of a copper plate or the like to both ends of a flexible conductor made of a flexible braided wire or the like by welding is used to oxidize the terminal plate and cause poor conduction. To prevent this, a terminal plate is welded and connected to both ends of the flexible conductor, and then the terminal plate is subjected to a surface treatment such as tin plating or silver plating.

ものとなるという問題点があった。However, in order to perform a plating process such as tin plating or silver plating on the terminal plate after welding and connecting the terminal plate to both ends of the flexible conductor, it is necessary to completely prevent a plating solution or the like from entering the flexible conductor. Since it must be performed, the work requires a great deal of attention and a long time, and there is a problem that the workability is extremely poor and expensive.

を有する可撓端子が得られる。A terminal plate having a welded portion and a connecting portion formed in a step shape on the plate surface and subjected to a plating process is completely covered with a shielding member, and then welded to both ends of a flexible conductor having both ends fixed. Therefore, workability is significantly improved, and there is no danger that the plating will be damaged by welding flame or heat during welding. In addition, since both ends of the flexible conductor are fixed, there is no bending or pinhole during welding. A flexible terminal having stable electrical characteristics over time does not occur.
