An imaging device is provided that can correct more accurately an image shake. The imaging device includes an imaging element taking an object image to generate image data, a gyro sensor unit including a gyro sensor, an image-shake correction unit holding the imaging element, moving the imaging element based on an output of the gyro sensor, and correcting a shake of an object image taken by the imaging element, and a mount base holding the gyro sensor unit and the image-shake correction unit.
