PROBLEM TO BE SOLVED: To adjust an optical axis without disassembling and reassembling an optical pickup. SOLUTION: In adjusting the position of an optical axis P of an optical pickup 20, in which a lens holder 22 holding a lens 21 for converging a laser beam is mounted freely rockingly on the base 25 through a suspension wire 23; the lens holder 22 is positioned relative to the base 25 so that the optical axis P of the lens 21 is arranged at a prescribed position; in this state, a solder ball 26 is melted in the base joining part of the suspension wire 23; and then, the solder ball 26 is solidified by isothermally cooling the base joining part of the suspension wire 23.
