PROBLEM TO BE SOLVED: To appropriately position a rotating mirror part while saving power. SOLUTION: The shake correcting device for an imaging apparatus includes: an imaging part; an MEMS mirror 300 having a mirror main body (1b) that is supported by a pan-axis torsion spring 302 and a tilt-axis torsion spring 306 so that it can freely rotate about two axes nearly perpendicular to each other; a driving coil for rotation about pan axis 304 and a driving coil for rotation about tilt axis 305 that are arranged in the magnetic fields generated by a magnet for rotation about pan axis 308 and a magnet for rotation about tilt axis 309, and also, disposed in the MEMS mirror; a rotational driving part to supply the power to the coils 304 and 305; a shake amount calculation part to detect the shake amount upon imaging an object by the imaging part; and a control part to control the amount and direction of the power supply from the rotational driving part to the driving coil for rotation about pan axis 304 and the driving coil for rotation about tilt axis 305 on the basis of the shake amount calculated by the shake amount calculating part, and to rotate the MEMS mirror in a direction P and a direction Y.
