PURPOSE:To cool active carbon grins enough by mixing a filler for improving heat conductivity in an adhesive applied to a cooled part in which the active carbon grains are embedded. CONSTITUTION:The surface of a cooled part 1 which is cooled to an extreme low temperature by means of coolant is coated with an adhesive 2 mixed with a filler for improving heat conductivity. Active carbon grains 3 are pushed thereon to be embedded therein. As time passes, the adhesive 2 is hardened and the active carbon grains 3 are fixed thereon. Consequently, the active carbon grains 3 which are embedded in the adhesive 2 whose heat conductivity has been improved are efficiently cooled and discharged after they adsorb gas molecules to be exhausted.
