PROBLEM TO BE SOLVED: To provide a pulse pipe refrigerating machine for increasing the usable area of a cooling side heat exchanger while having the similar surface area. SOLUTION: A hollow cylindrical regenerator 220 is formed, a pulse pipe 230 is inserted into the hollow section of the regenerator 220, and an inertance pipe 240 is allowed to communicate with the lower side of the pulse pipe 230 for composing a short, compact refrigerating mechanism 200, thus composing the pulse pipe refrigerating machine having the refrigerating mechanism 200.
