Abstract
An image blur correction device capable of effectively preventing occurrence of image blur with a simple configuration. A movable member holds a correction lens. A first drive section moves the movable member in a first direction orthogonal to a direction of an optical axis of the correction lens, and a second drive section moves the movable member in a second direction orthogonal to the direction of the optical axis. The first drive section includes a first vibrator unit and a first slider fixed to the movable member and in contact with the first vibrator. The second drive section includes a second vibrator unit and a second slider. When viewed in a direction of the optical axis, the first and second drive sections at least partially overlap each other.
