PROBLEM TO BE SOLVED: To provide a base for a light adapter capable of reducing energy cost by simple and inexpensive equipment without requiring equipment such as an expensive molding machine and a metal mold, excellent in dimensional stability, easy in control and easily manufacturable by performing dimensional finishing by removing a wire after forming a metallic or plastic wire in a bar shape as a matrix by electrocasting. SOLUTION: First of all, a thin bar is manufactured by electrocasting using a metallic or nonmetallic wire 9 as a cathode, and then, the wire 9 is removed by pulling out or pushing out or melting the wire 9, and then, the final finishing is performed by an automatic machine such as an NC machine. Generally, a wire being unmeltable in chemicals and having high tensile strength uses pulling-out or pushing-out, and a wire easily meltable in the chemicals uses melting. Since the wire 9 such as aluminum or the alloy and copper or the alloy easily melt in an acid or an alkali aqueous solution, removal by melting is mainly used. Actually, a strong alkali aqueous solution such as sodium hydroxide and potassium hydroxide of about 10 to 30 w/v% is used.
