PROBLEM TO BE SOLVED: To obtain a steam condenser for preventing water from returning to a steam supply side and at the same time for using a supply steam pressure from low to high pressure. SOLUTION: A non-return valve body 3 being elastically energized to the side of a steam outlet 4 by a coil spring 6 is arranged at the outlet side of the steam outlet 4. An elastic energization force adjustment means 10 for adjusting the spring force of the coil spring 6 is mounted. When the pressure at the side of an inlet 1 is reduced, the non-return valve body 3 closes the steam outlet, thus preventing the steam from returning to the side of the inlet 1.
