PURPOSE:To prevent both abnormal contact by sagging of an inner lead fine wire and the breaking of the inner lead fine wire by a method wherein the stream of a sealing insulator is suppressed by a protruding part. CONSTITUTION:A protruding part 25 is provided on a connecting conductive plate 11, an internal lead fine wire 22 passes above the protruding part 25. As the interval between a supporting plate and the connection conductive plate, where the protruding part is provided, is formed narrower than that of the other part, the state of flow of a sealing insulator becomes worse, and the pressure applied to the inner lead fine wire 22 is also reduced. As a result, the sagging of the inner lead fine wire 22 is prevented, a short-circuit is hardly generated, and the possibility of breaking of the inner lead fine wire 22 can be removed. |
