| titleOfInvention | Etching solution and method for manufacturing electronic substrate |
| abstract | The purpose of the present invention is to provide an etching solution that can selectively remove copper and/or a copper alloy from a base material containing copper and/or a copper alloy and nickel and/or a nickel alloy. The etching solution of the present invention is an etching solution for etching copper and/or a copper alloy from a substrate having the copper and/or the copper alloy and nickel or the nickel alloy, the etching solution containing an organic acid (A) and an oxidizing agent (B), the organic acid (A) having an acid dissociation constant (pKa) of-1.10 to 2.60, the first corrosion potential measured using nickel as a working electrode, Ag/AgCl filled with a saturated KCl solution as a reference electrode, and the etching solution as an electrolyte solution being 0.1V or more and 0.5V or less. |
