Zusammenfassung:PURPOSE:To form a TAB bump contact with good productivity and at a low cost. CONSTITUTION:The tip of the lead part 4 of a film carrier 3 made by the lamination of metallic fall 2 on insulating film 1 is subjected to bending so that a part of the lead part 4 is formed by projecting as a bump contact 5. This bending enables conducting a bump formation without requiring a process such as etching and many other processes.
