Abstract
A TAB tape has: a tape substrate of insulating material; a first wiring pattern of conductive material, the first wiring pattern being formed on one surface of the tape substrate; a second wiring pattern of conductive material, the second wiring pattern being formed on the other surface of the tape substrate; a conduction part that allows electrical conduction between the first wiring pattern and the second wiring pattern; and a stiffener that is adhered through adhesive to the other surface of the tape substrate. In the TAB tape, the second wiring pattern includes an insulating material filled in a groove region where no wiring pattern is formed around wiring patterns of the second wiring pattern.
