PROBLEM TO BE SOLVED: To provide a refrigerant-free refrigerating machine and a functional thermal binding body capable of reaching a very low temperature in a short time by a simple operation, having high operation efficiency and cooling efficiency at low costs, having a simple structure, and being easily maintained. SOLUTION: In the refrigerant-free refrigerating machine and the functional thermal binding body, a columnar first graphite bar 41 made of graphite having heat conductivity rapidly reduced in proportion to power of a temperature toward absolute zero, is disposed between a 40K plate 13 and a 4K plate 14, heat is conducted between the 40K plate 13 and the 4K plate 14 until the first graphite bar 41 reaches a first temperature equilibrium point when a temperature is lowered to 4K, and the 40K plate 13 and the 4K plate 14 are kept in a state of almost thermally separated from each other at the first temperature equilibrium point or less.
