とを特徴とする光ピツクアツプ。[Scope of Claim for Utility Model Registration] A movable substrate is rotatably mounted on a fixed substrate so as to be movable along the axis of rotation, and a device for reading is mounted on the movable substrate at a distance from the axis of rotation. In an optical pickup in which an objective lens is attached and the movable substrate is rotated and moved in the axial direction by electromagnetic drive means, the focusing coil to which the current of the electromagnetic drive means for moving the movable substrate in the axial direction is supplied does not have a bobbin. An optical pickup characterized in that the windings are sequentially welded to each other and a reinforcing adhesive layer is formed on the outer peripheral surface of the windings.
