To prevent a carrier tape from breaking during sealing with a resin, by omitting chip bonding, wire bonding, and molding in set areas including joints.
In the joint parts 39 of carrier tape 1, joint marks 6 are provided. After the detection of the marks, the carrier tape is skipped without carrying out chip bonding, wire bonding, and molding in set skip-areas, therefore heat is not applied to the joint parts, the carrier tape is prevented from breaking due to peel and separation of the joined tape, and an operation is continuously carried out. Because the joint parts 39 are not molded, failure in sealing with a resin does not occur and an IC module whose quality is stable can be produced. Also when failure marks are detected during a wire-bonding process, the carrier tape can be skipped.
