A bobbin of an optical pickup actuator having two lenses is provided to remove a winding guide unit which directly winds coils on the bobbin, and to install projections or concave grooves capable of installing previously made coils, thereby minimizing gaps between permanent magnets and the coils. Two or more lens setting units are capable of inserting lenses(401,402) into an upper part of a body in a length direction. Coil installation units install coils(420,430,440) formed on front and rear ends of the length direction of the body by inserting the coils(420,430,440). Wires are formed on an external side portion of the body pierce and penetrated through wire fixing units(403). The coil installation units are coil installation grooves(411) formed on front and rear side portions of the body.
