Provided is a dew condensation-free touch panel. Touch panel ( 200 ) has first transparent substrate ( 21 ) and second transparent substrate ( 22 ). First transparent substrate ( 21 ) has main surface ( 21 a) provided with first transparent conductive film ( 23 ). Second transparent substrate ( 22 ) has main surface ( 22 a) on which water vapor transmission preventive layer ( 40 ) as dew condensation prevention part, and second transparent conductive film ( 24 ) are provided in this order. Touch panel ( 200 ) has two regions: visible region ( 26 a) and invisible region ( 26 b) with region boundary ( 26 ) between them. Water vapor transmission preventive layer ( 40 ) is formed at least in visible region ( 26 a). First transparent substrate ( 21 ) and second transparent substrate ( 22 ) are fixedly bonded to each other via adhesive layer ( 31 ) in invisible region ( 26 b) or in the periphery of touch panel ( 200 ) so that first transparent conductive film ( 23 ) and second transparent conductive film ( 24 ) can have a predetermined distance therebetween.
