The touch panel has a structure such that a projection portion is provided on a second transparent substrate and a flexible printed-circuit board is bonded by thermocompression to the projection portion. By allowing width of a picture frame to be smaller in other portions than the projection portion, downsizing and a lighter weight of a touch panel-carrying apparatus can be attained.
