PURPOSE:To aim at improving resolution and increasing binding strength by forming an aelotropic conductive film by laminating first film of insulating resin with second film of insulating resin having conductive matter scattered and mixed in it. CONSTITUTION:First film 11 consists of insulating resin 14a, while second film 12 consists of insulating resin 14b having conductive matter 13 scattered and mixed in it, and both are put in layers. The conductive matter 13 is scattered on the side of a wiring substrate 23 in a resin layer 25 where the insulating resins 14a and 14b are integrated after they are heated and fused. This layer of resin 25 is filled integrally in the gap between a flexible printed substrate FPC21 and a wiring substrate 23 for holding electrode connection and protecting connected parts. The resin layer 25 flows between wiring patterns 22, 24 so they are connected with each other through the conductive matter 13. A film body with a high resolution and binding strangth can thus be obtained.
