A winding device of an optical pickup coil is provided to automate a process of winding a minute wire on a wiring boss of a bobbin to connect input/output lines of focusing/tracking coils with a lead wire, thereby lowering a defective proportion of a product. A wiring winding portion(1) consists of a transfer unit(11) and a winding unit(12). The transfer unit(11) comprises as follows. The first stepping motor(112) having a driving gear(111) is combined with the first bracket(113) fixed to an upper part of a frame(4). A transfer panel(117) where guide shafts(116,116') are fixed is connected with a lead screw shaft(115) having a driven gear(114) inserted into a lower part of the first bracket(113). The driving gear(111) and the driven gear(114) are coupled together by a timing belt(118). The winding unit(12) comprises as follows. The second stepping motor(122) is coupled with the second bracket(121) combined to sections of the guide shafts(116,116'). A winding rod(3) is combined with a motor shaft(123) of the second stepping motor(122).
