In a manufacturing method of a three-dimensional formed object, the method includes a first discharging in which a forming material is continuously discharged from a nozzle while causing a position of the nozzle to change with respect to the forming table in a first direction which is perpendicular to a top surface of the forming table to cause the forming material to be deposited in the first direction, a second discharging in which the forming material is continuously discharged from the nozzle while changing the position of the nozzle with respect to the forming table in a second direction which is parallel to the top surface of the forming table to dispose the forming material along the second direction, and repeating in which the first discharging and the second discharging are repeated.
