A positioning apparatus includes a first stage, capable of moving in a first
direction
and a second direction which is orthogonal to the first direction, a second stage,
arranged on the first stage and moved with the first stage, and capable of moving
in the first direction and the second direction and capable of mounting an object
to be adjusted in a position and a rotation, and a driving mechanism, arranged
on the first stage, and for moving the second stage relative to the first stage.
The driving mechanism includes a first electromagnet which generates first suction
power, a second electromagnet, provided opposite to and away from the first electromagnet,
which generates second suction power, and a core member, which is held movable
between the first and second electromagnets, and moves by being pulled in accordance
with the first and/or second suction power.
