NOVELTY - A carbon dioxide immobilization apparatus has micro reactor having micro flow path (4), unit for supplying gas raw material into micro flow path, unit for supplying liquid raw material into micro flow path, and photocatalyst layer (5) in inner surface of flow path. Gas raw material is carbon dioxide. Liquid raw material is material capable of reacting with carbon dioxide and producing organic compound. Supply units comprise a pipe flow in state into which liquid raw material flows along inner surface of flow path, and carbon dioxide flows through center portion.    USE - Apparatus is used for immobilizing carbon dioxide (claimed).    ADVANTAGE - The immobilization of carbon dioxide is efficiently and economically enabled. The carbon dioxide reduction product is efficiently produced in large amount by photocatalytic reaction during immobilization.    DETAILED DESCRIPTION - A carbon dioxide immobilization apparatus has a micro reactor having a micro flow path (4) in which a gas raw material and a liquid raw material are circulated as a reaction raw material, a unit for supplying gas raw material into micro flow path, a unit for supplying liquid raw material into micro flow path, and a photocatalyst layer (5) provided in inner surface of the micro flow path. The gas raw material is carbon dioxide. The liquid raw material is a raw material capable of reacting with carbon dioxide and producing an organic compound. The supply units comprise a pipe flow in state into which liquid raw material flows along inner surface of micro flow path, and carbon dioxide flows through center portion. An INDEPENDENT CLAIM is included for immobilization of carbon dioxide, which involves supplying liquid raw material to micro flow path having photocatalyst layer, advancing photocatalytic reaction, producing organic compound from carbon dioxide, and immobilizing carbon dioxide.
