Patent number: 10026523Abstract: A conductor includes: a transparent conductive film which is formed on a transparent substrate and includes a silver nanowire; and a metal film of which at least a portion is formed to overlap the transparent conductive film, in which a portion in which the transparent conductive film and the metal film overlap each other includes a buffer film which has adhesion to each of the transparent conductive film and the metal film and does not impede conduction between the transparent conductive film and the metal film. Preferably, the buffer film is, for example, an ITO film, and at this time, an upper surface of the transparent conductive film is a reverse-sputtered surface.Type: GrantFiled: April 14, 2015Date of Patent: July 17, 2018Assignee: Alps Electric Co., Ltd.Inventors: Yui Abe, Yoshihiro Taguchi, Mitsuo Bito, Yoshiyuki Asabe, Yasuyuki Kitamura, Tomoyuki Yamai, Koji Oguma, Tomofumi Oba

Patent number: 9965124Abstract: A method for patterning a light transmitting electrically conductive member uses a light transmitting laminate material in which an electrically conductive layer including an overcoat layer and silver nanowires embedded therein is formed on a surface of a light transmitting base film and includes a step of treating a surface of the electrically conductive layer which is not covered with a resist layer using an iodine solution to at least partially iodize the silver nanowires and a step of applying a thiosulfate solution to the surface of the electrically conductive layer which is not covered with the resist layer to remove a silver iodide exposed to a surface of the overcoat layer. Since a white cloudy or a whitened silver iodide is removed, the optical transmission characteristics of the non-electrically conductive region can be improved.Type: GrantFiled: January 25, 2016Date of Patent: May 8, 2018Assignee: ALPS ELECTRIC CO., LTD.Inventors: Tomoyuki Yamai, Mitsuo Bito, Yasuyuki Kitamura
