Abstract
A TAB (tape automated bonding) tape of high precision is formed without the deformations of its conductor pattern and the like and which is hermetically sealed with resin. The method for producing a TAB tape includes punching required holes, such as a device hole 14 and the like, in a metal plate 10 coated with an insulating adhesive layer 12 over the area where a conductor pattern is to be formed; and forming a required conductor pattern 24 by bonding a conductor metal foil onto the adhesive layer and by etching the conductor metal foil. Thus, the material cost of this TAB tape can be reduced and the production of this tape is facilitated.
