NOVELTY - A reaction apparatus (10) of biomass comprises saccharification reaction chamber (20) for producing saccharification solution, fermentation reaction chamber (22) for producing fermented solution containing alcohol, biomass supply port for supplying biomass to saccharification reaction chamber, and fermentation solution discharge port for taking out fermentation solution from fermentation reaction chamber. The saccharification reaction chamber and the fermentation reaction chamber are equipped with single reaction container mutually connected with V shape.    USE - Reaction apparatus of biomass for alcohol manufacture.    ADVANTAGE - The apparatus is simple and compact, alcohol can be manufactured continuously, and favorable performance of saccharification reaction and fermentation reaction is achieved.    DETAILED DESCRIPTION - A reaction apparatus (10) of biomass comprises saccharification reaction chamber (20) for producing saccharification solution, fermentation reaction chamber (22) for producing fermented solution containing alcohol, biomass supply port for supplying biomass to saccharification reaction chamber, and fermentation solution discharge port for taking out fermentation solution from fermentation reaction chamber. The saccharification reaction chamber and the fermentation reaction chamber are equipped with single reaction container mutually connected with V shape by inclining on both sides of connection part arranged at a boundary part. While spacing apart the lowest end position of the fermentation reaction chamber upwards rather than the lowest end position of the saccharification reaction chamber, corresponding to the lowest end of the fermentation reaction chamber, a communicating hole (42) for making the saccharification solution flow from the saccharification reaction chamber to the fermentation reaction chamber is formed in the connection part.
