PROBLEM TO BE SOLVED: To miniaturize a correction optical system for correcting a camera-shake and further to improve assemblability. SOLUTION: A third group barrel 3 holding a third lens group L3 is controlled to be driven by drive means in yaw and pitch directions orthogonal to an optical axis, respectively. The Y magnet and the Y yoke of the drive means in the yaw direction are fixed on the third group barrel 3, and a Y electromagnetic coil is disposed at a Y guide base 24 outside the Y magnet and the Y yoke, surrounding the third group barrel 3. As the drive means in the pitch direction, a P magnet and P yoke 29 are fixed to the Y guide base 24, and a P electromagnetic coil is fixed to a P guide base at an opposed position. Further, an FPC 34 for performing power supply, etc. is connected to an electromagnetic coil. A Y guide bar 25 and a P guide bar 30 are overlapped with projection regions onto planes orthogonal to the optical axis of the Y electromagnetic coil and the Y magnet, and the P electromagnetic coil and the P magnet, respectively. Further, the FPC 34 is overlapped with these two projection regions. COPYRIGHT: (C)2011,JPO&INPIT
