The activated carbon of the present invention has a gist of an equilibrium adsorption amount of 1,1,1-trichloroethane of 20 mg / g or more, and a pore volume of more than 20 mm 3 and less than 300 mm 3 in pore diameter of 0.04 cm 3 / g or more. In addition, according to the production method of the present invention, the phenol resin fibers are carbonized and subsequently activated one or more times to sequentially treat the phenol resin derivatives, and the one-time steam activating treatment is performed with any one activating as steam activating. At least one of a calcium compound and a potassium compound is affixed to a phenol resin derivative until it is carried out, and it has a summary to perform said one steam activating process, maintaining an adhesion state. |
