  • the motor 70 may be arranged by providing a hole through which the motor 70 passes through the substrate 230c, or the motor 70 may be arranged in an area where the substrate 230c does not exist. . Note that three or more substrates may be attached to the first fixed frame 40 .
  • the substrate 230c has surfaces 231c and 232c facing each other in the optical axis OA direction, and a plane PL11 including the surface 231c and a plane PL12 including the surface 232c are Intersects VCM 90X, 90Y. That is, substrate 230c radially overlaps VCMs 90X and 90Y. Also, the substrate 230c overlaps neither the VCM 90X nor the VCM 90Y in the optical axis OA direction.
  • a light receiving portion 242a of the position detection element 240a is provided at a position facing the VCM 90Y
  • a position detection element 240b is provided at a position facing the VCM 90X.
  • a plane PL17 including the light receiving portion 242a and a plane PL18 including the light receiving portion 242b intersect the magnets 52Y and 52X of the VCMs 90Y and 90X, respectively. In this way, even if only one substrate 230c is used, the substrate 230c surrounds part of the inner periphery of the first fixing frame 40 (but does not surround the entire inner periphery). It can be made thinner. Also in another embodiment, the plane PL12 including at least the surface 232c should intersect the VCMs 90Y and 90X.
  • the moving lens type blurring correction device 80 that drives the lens group L6 has been described, but the present invention is not limited to this, and can also be applied to a moving image pickup device type blurring correction device that drives the image pickup device. can be done.
  • the blur correction device described in the above embodiments can be applied not only to compact digital cameras and single-lens reflex digital cameras, but also to optical devices such as video cameras, binoculars, microscopes, telescopes, and mobile phones.
