A biomass feeding unit 12 that feeds a biomass material 11 containing cellulose, hemicellulose, and lignin under a normal pressure to put it under an increased pressure; a hydrothermal decomposition unit 17 that transports the fed biomass material from a lower side to an upper side in an apparatus body 13 by screw means 14, feeds pressurized hot water 15 from an upper side different from a feed position of the biomass material 11 into the apparatus body 13, performs hydrothermal decomposition while bringing the biomass material 11 into countercurrent contact with the pressurized hot water 15, and transfers a hot-water soluble component into a hot-water effluent 16, which is pressurized hot water to be discharged, so as to separate a lignin component and a hemicellulose component from the biomass material; a biomass solid discharging unit 18 that discharges a biomass solid 20 from the upper side of the apparatus body 13; and a slurrying vessel 21 communicating with the biomass solid discharging unit 18, into which water 19 is injected and the discharged biomass solid 20 is added to obtain a slurried biomass solid are provided.
