Abstract
A magnetic force drive device () has the first movable part () and the first driving unit (). The first movable part () has the first movable plate (), and a permanent magnet () that is magnetized in a direction substantially parallel to the first movable plate (), and is supported by the first frame body () and the first pair of beam parts (), so as to be able to oscillate around the Y axis, which is substantially parallel to the first movable plate () and substantially perpendicular to the direction in which the permanent magnet () is magnetized. The first driving unit () has a yoke (), and a coil () that magnetizes the yoke (). The yoke () has the first end part (), and a second end part () that is placed on substantially the opposite side of the first end part () against one magnetic pole of the permanent magnet (). The first end part () and second end part () are magnetized in mutually different polarities, and drive the first movable part () in the same oscillation direction.
