The support part has a facing surface opposing a side surface of the piled stack. The ultrasonic vibrator has a vibrating surface opposing the end in the direction of the piled stack and one end in the direction of the support part. The ultrasonic vibrator oscillates the vibrating surface along a line connecting the vibrating surface with a gap between the side surface of the piled stack and the facing surface of the support part.
