Abstract: Provided is a cryopump enabling the maintaining of a preset temperature during a preset time, even when turned off. The cryopump may comprise: a displacer which adjusts outside temperature by compressing or expanding a refrigerant existing therein; a thermal conduction part which transfers heat outside the cryopump to the refrigerant; and a thermal conduction buffer part which, if the displacer is turned off, absorbs the heat outside that is transferred to the refrigerant, and uses same as energy for changing a phase.
