Zusammenfassung:Provided is an exposure device having a structure advantageous for reducing vibration of an optical system. The exposure device for exposing a substrate includes: a projection optical system for projecting a pattern of a circular plate onto the substrate; a chamber for accommodating the projection optical system; a shutter which closes an opening provided in the chamber during exposure to transport the substrate; and an adjustment unit for adjusting the attenuation effect of sound from the outside of the chamber by the shutter.
