PROBLEM TO BE SOLVED: To provide a method for injection-molding a liquid addition curing type silicone rubber composition by an open gate mode mold which can reduce defective molding, and to provide a silicone rubber molding produced by the method. SOLUTION: The method for injection-molding the silicone rubber in which the liquid addition curing type silicone rubber composition is injected in the open gate mode mold and cured by heat includes a process (i) for injecting the liquid addition curing type silicone rubber composition having a fluidity, wherein the ratio (a/b) between viscosity (a) of a shear rate 10S<SP>-1</SP>at 23°C and viscosity (b) of a shear rate 100S<SP>-1</SP>is at least 2.5, in the open gate mode mold and a next process (ii) for decompressing.
