To provide a TAB tape that reliably achieves connection in a short time and establish the reduction of manufacturing time including the connection step as well as manufacturing cost accompanied therewith, and to provide method of manufacturing the same.

The insulating TAB tape 1 is formed of an insulating film substrate 2, wherein a conductor layer on one side of both sides thereof is a wiring layer which forms a wiring pattern body 3 and an outer leads 7 and 8 as an external connection terminal being connected with the wiring pattern body 3, and an inner lead 10, and that on the other surface thereof is a GND layer 4 or a conductor layer equivalent thereto. A part 11 to be heated in the external connection terminal is set to be heated to be connected with a connection terminal or the like (not shown) of an external printed wiring board, and a conductor blank portion 12 without a metal conductor such as a copper foil is provided in an area corresponding to the part 11 to be heated on one surface with the insulating film substrate 2 in between, in the GND layer 4 as the conductor layer on the other surface.
