The invention provides an absorption type carbon dioxide removal/concentration apparatus which can remove or condense carbon dioxide, can secure high recovery efficiency and can prevent a thermal deterioration of the amine absorbent to extend the life-span of the apparatus. The absorption type carbon dioxide removal/concentration apparatus has a honeycomb rotor (1) which holds an amine support solid absorbent. The honeycomb rotor (1) is divided into at least a processing zone (2) and a reproduction zone (4). An enthalpy (temperature and humidity) adjustment device is provided for the air for reproduction and/or the air to be processed. The apparatus can control the carbon dioxide absorbing performance and the concentration performance by passing processing and reproduction air through the corresponding zones.
