    • A regenerative refrigerator includes a cylinder configured to cause a refrigerant gas to adiabatically expand; and a regenerator tube connected to the cylinder and including a partitioning member. The partitioning member partitions an internal space of the regenerator tube into a first space in which the refrigerant gas flows and a second space filled with a regenerator material formed of gas. The regenerator tube is configured to accumulate, in the regenerator material, cold generated in the cylinder with adiabatic expansion of the refrigerant gas. The area of exposure of the partitioning member to the second space is greater than the area of exposure of the partitioning member to the first space.
