To provide an exposure device that reduces the occurrence of exposure failures.

An exposure device exposes a substrate with exposure light through a first liquid in a first immersion space. The exposure device includes: an optical member having an emission surface that emits exposure light; a first member that is arranged in at least part of the surroundings of an optical path of the exposure light and that forms the first immersion space of the first liquid; and a second member that is arranged on an outer side of the first member with respect to the optical path and that forms a second immersion space of a second liquid away from the first immersion space.
