PROBLEM TO BE SOLVED: To obtain a supercritical fluid injecting apparatus by which safety of the supercritical fluid injecting apparatus such as an injector can be improved, the injector can be prevented from being broken and molding can be prevented from becoming inferior caused by injection pressure of the supercritical fluid. SOLUTION: A supercritical fluid pressure control valve 7 is fitted with a pressure detector 8A with an external signal outputting function and the outputting signal is taken in a controller 10A to always monitor the injection pressure of the supercritical fluid, and when an abnormal pressure is generated, an alarm signal is outputted to an alarm unit 20 and a stop command is outputted to a screw driving device 3 to stop driving.
