摘要： An object of the invention is to provide a method for producing a multiaxial-inlay knitted fabric base material with high productivity, a multiaxial-inlay knitted fabric base material that enables to produce a molded article, which is excellent in surface smoothness and has a high strength and a high elastic modulus, and a fiber-reinforced composite material including the multiaxial-inlay knitted fabric base material. a method for producing a multiaxial-inlay knitted fabric base material, the method comprising: conducting a pressurization and heating treatment to a multiaxial-inlay knitted fabric base material precursor (1) that includes a multiaxial stack (30) and a stitching thread (42) that may be formed into a restraining knitted fabric (40), which is disposed to restrain the multiaxial stack (30), in a specific condition, and a multiaxial-inlay knitted fabric base material in which an opening width (50) of the reinforcement fiber constituting the multiaxial-inlay knitted fabric base material is equal to or less than a nominal diameter of the stitching thread (42) that may be formed into a restraining knitted fabric (40).
