PROBLEM TO BE SOLVED: To provide a micro-actuator capable of obtaining a satisfactory slider position adjustment function and resonance function when the micro-actuator is driven. SOLUTION: The micro-actuator comprises two side arms in which a rotation extension portion is provided at least one first end portion a supporting member including a rotatable base plate provided between the two side arms, a pair of linking members provided so that the rotatable base plate is connected to second end portions of the side arms, and at least one piezoelectric element connected to the whole side arms and the rotation extension portion of the side arms. When the at least one piezoelectric element is expanded, the rotatable base plate is rotated in a first direction. When the at least one piezoelectric element is contracted, the rotatable base plate is rotated in a second direction. COPYRIGHT: (C)2007,JPO&INPIT
