PROBLEM TO BE SOLVED: To provide an object lens driving device which drives an object lens for condensing light onto the recording surface of an optical disk even in the tilt direction of the optical axis of the object lens in addition to the focusing direction and the tracking direction in order to perform excellent recording/ reproducing in the optical disk device made high in density. SOLUTION: In the object lens driving device, four linear supporting members are fixedly inserted into a hole provided in the side surface of a lens holder, and two supporting members, each in which a coil shaped part or a bending part is provided at its middle part, are fixed to a groove provided in the side surface of the lens holder. Also, two supporting members, which are fixed along the groove provided in the side surface of the lens holder, are fixed to the side nearer to the object lens than the center of the fixed position of four linear supporting members in the direction of the optical axis of the object lens.
