PROBLEM TO BE SOLVED: To provide a small-sized and light-weight objective lens driving device capable of maintaining required performance as the objective lens driving device even in a high frequency band. SOLUTION: An objective lens 2 for converging a light beam on a recording surface of a recording medium and an objective lens hold body 1 for holding the objective lens 2 are integrally formed using material different from each other. Thus, the objective lens driving device excellent for the positional precision and the slope precision of the objective lens 2 and integrally driving the objective lens 2 and the objective lens hold body 1 is obtained. Further, since the objective lens driving device doesn't use adhesive and an attaching tool such as an attaching screw the device is miniaturized and lightened without being affected by the adhesive and necessitating a space for adhesion. |
