Zusammenfassung:	PURPOSE:To obtain a catalyst with high catalytic ability and reduce catalyst cost by using copper sulfate recovered from a copper etching waste solution with a concentration lower than a prescribed value for preparation of the title precursor. CONSTITUTION:A methanol synthesis catalyst is prepared by using a copper sulfate recovered from a very economic copper etching waste solution as a copper source and copper, zinc, and aluminum compounds or a boron compound. In this case, the concentration of the waste solution is made to be
