PURPOSE: To perform continuous tests, inspections and the like of an electric circuit, by filling plastics to a hole, which is provided at a head part of a support lead as a unitary body, firmly holding each half-finished product, and feeding the half-finished product in a tape shape.
CONSTITUTION: A support lead 12 is protruded to the inside from a metal tape 2. The support lead 12 has a leg part 12a, which is linked to the metal tape 2, a head part 12b, which is linked to the leg part 12a and a hole 12c at the approximately central part. A connecting tape for automatic gang bonding 1 comprising the metal tape 2 is continuously fed to a bonding process. Each inner lead part 10a is connected to an electrode 8a of a semiconductor element 8. The head part 12b of the support lead is not contacted with the semiconductor element 8 but terminated before the element 8. Plastic sealing is performed on the half-finished product, whose bonding is finished. In the support lead 12, the head part 12b and the hole 12c are filled with plastics, and the bonding becomes extremely rigid.
