Abstract: [Problem to be Solved] To develop a material of aluminum anode-oxidization layer with an antistatic performance and hardness.
[Means for Solving Problem] The present invention provides a material having the combination of antistatic, electro-magnetic shield, and electric conductive properties immediately provided to practical use which are not known conventionally by forming 10-1000 cracks having a width from 0.1-10 μm per arbitrary one end face of 1 cm2, depositing or precipitating metal in and nearby the cracks, and then forming between a substrate and a surface an electric-conductive layer not more than 103Ω.
