PROBLEM TO BE SOLVED: To automatize assembling while simplifying constitution by preparing in a holder holding an objective lens a flange deciding a position of a focus coil, a winding bed deciding the position of a tracking coil and a fixing part to which a leaf spring is fixed. SOLUTION: One end part of a leaf spring 48 is fixed to a holder 60, the other end part is fixed to a suspension base, and whereby the holder 60 is supported in a floating state so as to be movable to the suspension base. Winding beds 65 are formed in a respective facing position in flanges 64 provided in both end parts of a body part 62 of a holder main body 61. A focus coil 63 is wound and next a tracking coil 66 is wound using an automatic winding machine. At this time, the winding position of the focus coil 63 is decided by the flange 64 and the winding position of the tracking coil 66 is decided by the winding bed 65. Thereafter, a lens 41 is fixed to the body part 62 of the holder main body 61, and a leaf spring 48 is fixed to fixing parts 67, 68 formed in the side part of the flange 64. |
