1. An optical element driving device, comprising:
a fixed portion having a main body portion provided with a pair of bearings aligned across a through hole;
an optical element in which liquid is encapsulated between a first end surface and a second end surface opposite to each other and the first end surface is fixed to the fixed portion;
a first movable portion having a main body portion provided with a through hole corresponding to the through hole of the fixed portion and a pair of first rotation shafts aligned across the through hole, and a pair of second rotation shafts arranged to orthogonal to the pair of first rotation shafts, wherein the first movable portion is rotatable supported by the pair of bearings of the fixed portion and rotatable around an axis of the first rotation shaft; and
a second movable portion having a main body portion provided with a through hole corresponding to the through hole of the first movable portion and a pair of bearings supporting rotatable the pair of second rotation shafts of the first movable portion, and fixing the second end surface of the optical element by the main body portion;
a first driving portion having a first magnet fixed to a first side plate portion connected to the main body portion of the first movable portion and a first coil arranged at a first FPC (Flexible Printed Circuit board) fixed to the fixed portion, the first coil arranged opposite the first magnet, the first driving portion rotationally driving the first movable portion around the axis of the first rotation shaft; and
a second driving portion having a second magnet fixed to a second side plate portion connected to the main body portion of the first movable portion, the second side plate portion arranged to orthogonal to the first side plate portion and a second coil arranged at one end of a second FPC (Flexible Printed Circuit board) having the one end fixed to the second movable portion and the other end fixed to the first FPC, the second coil arranged opposite the second magnet, the second FPC provided with a strip-like portion in a swirl shape, the second driving portion rotationally driving the second movable portion around the axis of the second rotation shaft.
