PROBLEM TO BE SOLVED: To provide a manufacturing method for ferro-coke attaining effective utilization in a ferro-coke manufacturing process by using low temperature carbonization tar generated in the ferro-coke manufacturing process as a binder of a ferro-coke material molded article. SOLUTION: In the method for manufacturing the ferro-coke by carbonizing the molded article obtained by mixing/molding a carbon-containing substance and an iron-containing substance, the manufacturing method for the ferro-coke characterized in that the low temperature carbonization tar generated at the carbonization is reformed to make it to heavy weight reformed tar and the reformed tar is mixed with the carbon-containing substance and the iron-containing substance while making the reformed tar as the binder to mold the molded article is used. Reforming of the low temperature carbonization tar is preferably performed by heating it to 200-350°C and blowing air to it, and the reformed tar preferably has a softening point in a range of a stirring temperature±20°C when the reformed tar is mixed with the carbon-containing substance and the iron-containing substance, and is molded.
