PROBLEM TO BE SOLVED: To provide an efficient method, permitting a treatment in a shorter time and at a lower cost, for a hydrolysis treatment of bamboo, wood, and other plant biomass using a subcritical fluid or a supercritical fluid. SOLUTION: Bamboo, wood and other plant biomass are subjected to a hydrolysis treatment using a subcritical fluid or a supercritical fluid in a solid shape as it is without finely dividing by chipping, crushing or other methods by employing a pretreatment technology where an impact wave is sent to the biomass to selectively destroy a blocked cellular pore with a rim or a cell membrane in the material thereby permitting ready penetration of the subcritical fluid or the supercritical fluid such as an alcohol, water, carbon dioxide gas and the like.
