Abstract

According to one aspect of the present invention, a conductive film (10) is provided, which is a conductive film (10) having a first conductive part (11) and a second conductive part (14), wherein the second conductive part ( The surface (14A) of 14) constitutes at least a part of the surface (10A) of the conductive film (10), and the surface (11A) of the first conductive part (11) constitutes at least a part of the back surface (10B) of the conductive film (10) , the first conductive part (11) and the second conductive part (14) comprise conductive fibers (15), (17) respectively, and the surface resistance value of the second conductive part (14) is the surface of the first conductive part (11) Within ±30% of the resistance value.

Description

[0001] References to related applications [0002] This application enjoys the benefit of the priority of Japanese Patent Application No. 2017-247306 (filing date: December 25, 2017) and Japanese Patent Application No. 2017-254135 (filing date: December 28, 2017), which are earlier Japanese patent applications , the disclosure of which is incorporated by reference in its entirety as a part of this specification. technical field [0003] The present invention relates to a conductive film, a sensor, a touch panel, an image display device, and a conductive film with a protective film. Background technique [0004] Conventionally, conductive films have been widely used in touch panels and the like. The conductive film includes a translucent substrate and a conductive portion provided on one surface of the translucent substrate, and indium tin oxide (ITO) is mainly used for the conductive portion of the conductive film. [0005] However, since ITO has no flexibility, when a fle...
