Abstract:
Disclosed are: a microetching agent which can form roughened shapes less affected by differences in the crystallinity of the copper and with which roughened shape excellent in terms of adhesiveness to resins, etc. can be formed on either electrolytic copper or rolled copper; and a method for producing a wiring board which includes a step of roughening a copper surface using the microetching agent. In the present invention, the microetching agent for copper is an acidic aqueous solution containing an inorganic acid, a cupric ion source, a halide ion source, and a polymer. The polymer has a functional group containing a nitrogen atom. It is preferable that the microetching agent contain a sulfate ion source.

Claim (Index 11):
The method for producing a wiring board according to  claim 9 , wherein\n a replenishing liquid is added into the microetching agent during the roughening the copper layer, the replenishing liquid is an acidic aqueous solution comprising of an inorganic acid, a halide ion source, and a polymer, and the polymer in the replenishing liquid is a water-soluble polymer having a weight-average molecular weight of 1000 or more, and is selected from a group consisting of: a polymer having a quaternary ammonium group in a side chain, and a polymer having a repeating unit represented by the following formula (V): wherein in the formula (V), R 14  is a hydrogen atom or a chain or cyclic hydrocarbon group optionally having a substituent; m is an integer of 0 to 2; X 12  and X 13  are each independently a single bond or a divalent linking group.
