Abstract
The present invention is a lens driving device comprising first driving coilswhich relatively moves a lens holderagainst a base partalong X axis perpendicular to an optical axis of a lens, and second driving coilswhich relatively moves a lens holderagainst a base partalong Y axis perpendicular to an optical axis. At the base part, an opening partis formed where a part of the lensis to be inserted in a movable manner along the driving plane. The oblique diameter Dxyand Dxyof the opening partalong the oblique direction positioned at the middle of X axis and Y axis, is larger than the first inner diameter Dx along X axis direction of the opening part, and also larger than the second inner diameter Dy along Y axis direction of the opening part. At the base part, the cylinder shape projection partis formed along the periphery of the opening part
