Abstract: PURPOSE:To improve appearance and reduce dipping time and then improve productivity by performing oxidation treatment of the copper circuit of the inner layer wiring board in alkali aqueous solution containing persulfate, forming a specific amount of copper oxide layer, and then dipping it into acid aqueous solution and then eliminating the coating of copper oxide. CONSTITUTION:A copper circuit is formed on the surface of an inner layer wiring board. The wiring board is subjected to oxidation treatment in alkali aqueous solution containing persulfate such as potassium persulfate to enhance adhesion with prepreg. The oxidation treatment forms copper oxide layer consisting of copper oxide and cuprous oxide on the surface of the copper circuit. The oxidation treatment causes fine protrusions on the surface of the copper circuit, thus forming the copper circuit whose surface is rough. The amount of formed copper oxide layer is 75mg/dm<2> or more. After the oxide layer is formed, it is dipped in oxidation aqueous solution, thus dissolving and eliminating the coating of the copper oxide within the copper oxide layer while causing coprous oxide to remain.

Thus, a new standard evaluation value is calculated.  In this case, a picture element after motion compensation is used as a past picture element by the discrimination section 16. A quantization object minimizing the new standard evaluation is extracted at the output terminal 14 selectively.
