A release device for releasing a specific gas component from a rich absorption liquid which is an absorption liquid containing the specific gas component absorbed therein, the release device including a channel structure internally having a release channel which is connected to a rich absorption liquid supply unit so as to receive the rich absorption liquid supplied from the rich absorption liquid supply unit and connected to a liberating agent supply unit so as to receive a liberating agent supplied from the liberating agent supply unit, the liberating agent having a boiling point lower than a boiling point of the rich absorption liquid and being incompatible with the rich absorption liquid. The release channel is a microchannel configured to guide the received rich absorption liquid so that the received rich absorption liquid releases the specific gas component while flowing. The release channel has a treatment channel part which guides the rich absorption liquid and vapor of the liberating agent while bringing the rich absorption liquid and the vapor of the liberating agent into contact with each other so that the specific gas component is liberated from the rich absorption liquid to be transferred to the vapor of the liberating agent.
