An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. An insulating adhesive layer 12 and a conductive layer 13 are provided in stripes on a plastic film substrate 11. The conductive layer 13 has a double structure. The conductive layer 14 on the substrate 11 side is provided continuously and has almost no adhesive force, but is formed to have low electrical resistance. The conductive layer 15 on the surface side is provided alternately and intermittently with the insulating adhesive layer 12 so that it is surrounded by the insulating adhesive layer 12, and has a certain degree of adhesiveness.

上する。 When the insulating adhesive layer 12 and the conductive layer 15 are provided with adhesive properties using a hot melt agent, they can be bonded to glass such as a liquid crystal display element, a PCB, etc. by applying appropriate pressure and temperature. In this case, electrical connection is made using the conductive layer 15 as a contact and the conductive layer 14 as a wiring. Further, since the adhesive is also bonded by the adhesive layers 12 provided alternately with the conductive layers 15, the adhesiveness with the terminal portion of the liquid crystal display element or the like to be connected is doubled, and reliability is improved.
