Abstract
Provided is a high-quality capacitive touch panel that prevents surface roughness of a rear surface of a resin layer from being visible. The resin layer is adapted to eliminate a level difference caused by a decorative layer formed at an outer edge of a rear surface of a transparent panel substrate. The capacitive touch panel includes a planarization resin layer 4 and a sensor section 5. The planarization resin layer 4 is formed on a region inside a level difference caused by a decorative layer 3 formed on the transparent panel substrate 2 and a rear surface of the decorative layer 3 on a rear surface of a transparent panel substrate 2 having flexibility. The sensor section 5 includes transparent electrode layers 5a and 5b formed on a rear surface of the planarization layer 4. The planarization resin layer 4 has a rear surface to which a planar surface is transferred by pressurization and that has unevenness with a maximum height of 0.1 μm or less.
