    Abstract: An etchant for copper and copper alloys, includes an aqueous solution containing: 14 to 155 g/liter of cupric ion source in terms of a concentration of copper ions; 7 to 180 g/liter of hydrochloric acid; and 0.1 to 50 g/liter of azole, the azole including nitrogen atoms only as heteroatoms residing in a ring. A method for producing a wiring by etching of copper or copper alloys, includes the step of: etching a portion of a copper layer on an electrical insulative member that is not covered with an etching resist using the above-described etchant so as to form the wiring. Thereby, a fine and dense wiring pattern with reduced undercut can be formed.

    Abstract: An object is to provide, for example, a method for manufacturing a film-forming substrate that can sufficiently improve both bleeding of a resin composition and adhesion between the resin composition and a metal substrate surface. For example, provided is a method for manufacturing a film-forming substrate having a film of a resin composition formed on a metal substrate surface, the method including: an etching step of etching a metal substrate surface with a micro-etching agent; a surface treatment step of bringing the etched metal substrate surface into contact with a surface treatment agent to perform a surface treatment such that a contact angle of water on the surface is 50° or more and 150° or less; and a film forming step of forming a film of a resin composition on the surface-treated metal substrate surface by an inkjet method.
