PROBLEM TO BE SOLVED: To improve a yield by fixing the device across a holder and supporting body in the state of keeping linearity of suspension wires for supporting a holder of an object lens to a supporting body, with respect to an object lens driving device as an optical head driving device. SOLUTION: In this manufacturing method, a holder 3 of an object lens and a supporting body 7 are positioned at predetermined corresponding positions on a positioning rack, and middle parts almost over the whole length between the parts tacked on the holder 3 and the supporting body 7, of the four suspension wires 8 tacked beforehand on both ends of the holder 3 and the supporting body 7, are positioned and held by vacuum-sucking linearly in the longitudinal direction by a sucking holder 30 of a positioning holding device 29, and in this state, the four suspension wires 8 are fixed by soldering across the holder 3 and the supporting body 7.
