Abstract
There is provided a spacerless input device that suppresses reflection at an interface, prevents generation of Newton's rings, improves visuality, does not operate erroneously even with no provision of a dot spacer, and has a pressure sensitive function even responsive to input with a solid matter. In an input device of a resistive film type accepting multiple touches, a pressure-sensitive conductive layer and an intermediate layer are filled in a gap between a surface provided with an upper transparent electrode group of an upper transparent electrode base member and a surface provided with a lower transparent electrode group of a lower transparent electrode base member.
