A process for producing a polymer/filler composite material includes a mixture forming step in which there is obtained a mixture of a flake-like filler and a polymer material, and the mean area (L 2 ), mean thickness (d) and volume fraction (c) of the flake-like filler in the mixture satisfy the following equations (1), (2) and (3): n 500 nm 2 ≦L 2 ≦100 μm 2 (1) n d≦L /20 (2) n 0.2 d/L≦c ≦4 d/L (3), n and a deforming step of applying deformation to the mixture at a strain rate of no greater than 10 s −1 . |
