Summary:[Task] It is to propose a ferrocoke manufacturing method effective for manufacturing high-strength ferrocoke without causing fusion between mutual shaped bodies. [Solution] In a ferrocoke manufacturing method by shaping and carbonizing a mixture of coal and iron ore, a hardly softening coal having a button index (CSN) of not more than 2.0 is used as the coal. In a preferable example, the coal is a blend of hardly softening coal and easily softening coal, and the hardly softening coal is a coal having a button index (CSN) of 1.0 and a volatile matter of not less than 17%, and the easily softening coal is a coal satisfying that a value obtained by multiplying CSN of easily softening coal by a blending ratio of easily softening coal in all coals is a range of 0.3-5.2. In another preferable example, the coal is a blend of hardly softening coal and easily softening coal, and the hardly softening coal is a coal having a button index (CSN) of 1.5-2.0, and the easily softening coal is a coal satisfying that a value obtained by multiplying CSN of easily softening coal by a blending ratio of easily softening coal in all coals is nit more than 5.0.
