Apparatus for use in the component extraction method and the method of the material to be treated

Component extraction method from the treated material, after the material to be treated along the internal channel of the container (8) (8c) (10) and an adsorbent (12) arranged alternately in the layered container (8) supplying a high-pressure solvent into the internal flow passage (8c), a predetermined component from the material to be treated (10) to extract the solvent, the predetermined component in the solvent is removed by adsorption to the adsorbent (12).
