PURPOSE: An injector head of a liquid propellant rocket combustor is provided to prevent oxidizer and fuel from being leaked and mixed inside the injector head by separately including an oxidizer injector and a fuel injection nozzle. CONSTITUTION: An injector head of a liquid propellant rocket combustor comprises an injection plate(110), a partition plate(120), a fuel injection nozzle(130), and an oxidizer injector(140). The injection plate constitutes the upper side of the combustion chamber and has through-holes(111). The partition plate is apart from the upper part of the injection plate to form a space between the partition plate and the injection plate. The fuel injection nozzle injects fuel supplied from a fuel supply manifold to the combustion chamber. The upper side of the fuel injection nozzle is coupled with the lower side of the partition plate and the lower side of the fuel injection nozzle is inserted into the through-hole. The oxidizer injector injects oxidizer supplied from an oxidizer supply manifold.
