Abstract

PURPOSE:To obtain easily the synthetic resin base having high precision and complicated fine flow pathes by only one process of forming by a method in which the object in which the surface of synthetic resin is smoothly finished by secondary working, is used as a master and the mold produced by electroforming or mold casting treatment, is used. CONSTITUTION:Flow path grooves 2 are formed as protrusions, and the flat plate surface 5 to be welded is machined by a milling machine, etc. Then the flow path grooves 2 are formed as recessed portions. The surface of the mold 7 for molding a master is transferred to the flat plate surface 5 to be welded. Secondary working is applied to the master 8 of a formed object, and the flat plate-surface 5 to be welded is smoothly finished. Here, for the secondary working, the working by a precision lathe or the grinding operating by a lapping sheet is effective a base is produced by electroforming treatment, while the master 9 for the second working is used. The flow path grooves 2 are formed as protrusions, and since the surface of the master 9 for the secondary working is transferred to the flat plate surface 5 to be welded, it is smooth. This base may be welded to the flat plate without necessity of finishing into a smooth surface by the secondary working of the formed object, whereby the stability of quality is advantageous, and the cost of production is low.
