A vacuum actuator includes a vacuum partition wall, the interior of which can be evacuated to a vacuum, a rotor supported by the vacuum partition wall to be free to rotate, a permanent magnet provided on the outer peripheral surface of the rotor, a coil opposed to the permanent magnet, and a stator provided with the coil. The stator and the vacuum partition wall are formed integrally with each other.

A substrate conveyance apparatus includes a first driving shaft, an arm portion having one end connected to the first driving shaft, a substrate holding unit capable of holding a substrate, and a connecting portion that connects the other end of the arm portion and the substrate holding unit. The connecting portion includes a rotating support portion that supports the substrate holding unit rotatably with respect to the arm portion, and a moving unit that moves the substrate holding unit upward or downward with respect to the arm portion in the direction of the rotating shaft about which the substrate holding unit is rotated by the rotating support portion.
