  • Patent number: 11869834
    Abstract: An electroconductive substrate, including: a base material; a foundation layer disposed on the base material; a trench formation layer disposed on the foundation layer, and an electroconductive pattern layer including metal plating. A trench including a bottom surface to which the foundation layer is exposed, is formed. The trench is filled with the electroconductive pattern layer. The foundation layer includes a mixed region which is formed from a surface of the foundation layer on the electroconductive pattern layer side towards the inside thereof, and contains metal particles which contain a metal configuring the electroconductive pattern layer, and enter the foundation layer.
    Type: Grant

  • Patent number: 11410855
    Abstract: A method of producing an electroconductive substrate including a base material, and an electroconductive pattern disposed on one main surface side of the base material includes: a step of forming a trench including a bottom surface to which a foundation layer is exposed, and a lateral surface which includes a surface of a trench formation layer, according to an imprint method; and a step of forming an electroconductive pattern layer by growing metal plating from the foundation layer which is exposed to the bottom surface of the trench.
