れていた。2. Description of the Related Art As shown in FIG. 2, a conventional method of combining leads (hereinafter referred to as "leads") of a fluorescent display is such that two leads A1 and leads B2 of the same shape are both face-up, and each lead The terminals 3 were arranged so as to face each other.

【発明が解決しようとする課題】この従来のリードの組
合せ方法では、図２に示すように、不必要な部分が多い
為にａ×ｂの面積が大きくなり、素材のシートの単位面
積から得られるリードの取り数が減少するという問題点
があった。In this conventional lead combination method, as shown in FIG. 2, since there are many unnecessary portions, the area of a × b becomes large, and the area of a material sheet is obtained. There was a problem that the number of leads taken was reduced.
【０００４】本発明の目的は、素材シートの単位面積か

る。According to the present invention, in a lead of a fluorescent display tube in which two sets of lead terminals are combined and molded at the same time, one of the two sets of lead terminals is face-up and the other is face-down. Then, the respective lead terminals are arranged so as to be located between the respective lead terminals.

つながるという効果を有する。As described above, according to the present invention, one lead is combined face-up and the other lead is combined face-down to form two sets of leads, thereby reducing the area axb in FIG. Therefore, the number of leads obtained from the unit area of the sheet of material is increased, and the cost per lead is reduced.
