Beschreibung
Zusammenfassung:	The present invention pertains to a degassing device for removing gas such as dissolved gas and microbubbles in a liquid and to a coating device comprising the degassing device, and the purpose thereof is to remove the gas contained in the liquid in a short time. Specifically, the degassing device is configured to comprise: a supply channel in which the liquid flows; a microchannel element that is provided downstream of the supply channel and that has a plurality of microchannel holes with a channel area smaller than the supply channel; a tank that has an expansion space therein and that stores the liquid passing through the fine channel holes; and a pressure reducing mechanism that reduces pressure in the expansion space.
