<P>PROBLEM TO BE SOLVED: To provide a device for removing deposits, which can electrically neutralize particles under easy-to-remove posture and can remove particles efficiently. Ž<P>SOLUTION: The device includes a tilt mechanism (rotation/tilt mechanism 14) for holding a substrate (wafer 10) and directing the extending direction of the substrate in the gravity direction, an electrostatic charging mechanism for making an electrostatic charging state nearby the surface of the substrate positive or negative by blowing electrostatically charged gas to the substrate, and an electrostatic discharging mechanism for electrically neutralizing the electrostatic charging state nearby the surface of the substrate by grounding the substrate to a zero potential after blowing gas electrostatically charged to the opposite polarity from the electrostatic charging polarity of the substrate and deposits.
