PROBLEM TO BE SOLVED: To provide an injection molding method which can suppress the occurrence of distortion and a deterioration in configuration transferabilities. SOLUTION: The method for injection-molding an organic, inorganic composite material in which fine inorganic particles 100 nm or below in particle size are dispersed in a thermoplastic resin includes the process for packing the composite material in the cavity 26 of a die 1 and the process for taking out a molding made of the composite material from the cavity 26 of the die 1. When the glass transition temperature of the thermoplastic resin is Tg, in the process for packing the composite material, the surface temperature of the cavity 26 of the die 1 is adjusted to be Tg+15C°to Tg+70°C.
