Imaging element unit, shake correction device, and imaging apparatus

A shake correction device comprising:

• a fixed unit that includes a magnet member and a yoke member;
• and
• a movable unit that includes an imaging element unit and a coil member,
• wherein the imaging element unit includes:
• an imaging element;
• an optical member that is disposed on an imaging surface side of the imaging element;
• and
• a vibration applying device that is disposed on a first surface of the optical member,
• wherein a second surface of the optical member opposite to the first surface has a first region including a region overlapping with the vibration applying device in a case of being seen through in an optical axis direction of the imaging element, and a second region that is a region other than the first region,
• the first region and the second region have different surface characteristics, and
• an image shake is corrected by moving the movable unit in a plane intersecting an optical axis of the imaging element.
