To provide a manufacturing method for coke capable of producing highly strong coke by reducing the coarse pore amount remaining in the coke without depending on caking coal while using conventional equipment without the need of special carbonization furnace.
The manufacturing method for coke includes a step of carbonization of coal in an atmosphere provided with vibration control of the atmospheric pressure in the heating space in producing coke by carbonization of coal placed in a heating space. The vibration control of the atmospheric pressure is carried out preferably so as to include at least a period with the coal in a softened molten state. The pressure vibration control is carried out preferably with the difference between the maximum value and the minimum value of the atmospheric pressure in the heating space of 100 Pa or more, and the interval of the maximum value and the minimum value being 10 seconds or less.
