PURPOSE:To provide electroconductive resin light in weight, strong, and no risk of breakage when filled, by using electroconductive fiber consisting of polyamid fiber covered with Ni. CONSTITUTION:Existing electroconductive resin contains 0.5-20wt.% electroconductive fiber consisting of Ni-covered polyamid fiber of 0.1-10mm long and 1-100mum in dia. When the length exceeds 10mm, it is hard for the resin to contain it to cause the electroconductivity of the resin to become un even, while the effect of fiber will go out when shorter than 0.1mm, and electroconductivity can not be provided unless the content of the resin is in creased. Smaller dia. of the fiber than 1mum causes hard to disperse, while exceed ing 100mum requires more content than 40% by weight in order to equip electroconductivity. Thereby there is less risk of breakage at the time of includ ing in the resin, that should ensure uniform electroconductivity.
