ABSTRACT:
An upper substrate that has upper conductive layer formed on a bottom surface thereof, is bonded to lower substrate, that has lower conductive layer opposed to the upper conductive layer with a predetermined space held therebetween, on a top surface of lower substrate by an adhesive layer that is made of a thermoplastic resin containing a tackifier dispersed therein, with a bonding property of the adhesive layer being enhanced by pressing. Addition of the tackifier increases flexibility of the adhesive layer and performs bonding with a large adhesive area at pressing. Thus, a width of the adhesive layer can be as small as approximately 1 to 1.5 mm. This can provide a smaller touch panel ensuring a predetermined touch sensitive area.
