PROBLEM TO BE SOLVED: To provide an objective lens actuator which is excellent in adhesive workability to enable accurate positioning and bonding of tips of wires to both side wall sections of a lens holder. SOLUTION: The objective lens actuator constituted by forming wire tip positioning grooves 1f in both side wall sections 1a of the lens holder 1 holding the objective lens 5 and inserting the tips of the wire 4 projecting forward through gel filling sections 2a on both sides of a gel box 2 into the positioning grooves 1f and bonding the tips by an adhesive 8 is provided. The wire tip positioning grooves 1f can be easily and accurately molded by a forming die in molding the lens holder 1 with a synthetic resin. Even if the positioning accuracy is enhanced by narrowing the groove width, the inflow of the adhesive 8 or the wrap-around thereof to the wire circumference is good and therefore, the objective lens actuator which is high in the positioning accuracy and is excellent in the workability and strength of adhesion is obtained.
