| titleOfInvention | Method for producing printed wiring board, and printed wiring board |
| abstract | This method for manufacturing a printed wiring board comprises: a step for preparing a metal foil-clad laminate in which a metal foil having an arbitrary thickness (Db) in a range of from 3 to 20 μm and an insulating resin layer are laminated; a step for forming a resist layer on a surface of the metal foil; a step for forming a resist pattern by subjecting the resist layer to exposure/development; a step for forming metal wires by etching the metal foil where the resist pattern is not formed by spraying an etching solution; and a step for removing the resist layer. In the step for forming the metal wires, the metal wires are formed such that the metal wires have a gap (S) of 15 to 50 μm, and that a ratio (S/Db) of an arbitrary thickness (Db) of the metal foil and the gap (S) between the metal wires is greater than 1.6. |
