A three-dimensional shaping device includes: a plasticizing unit; a nozzle configured to dispense a plasticized material from a nozzle opening toward a stage; a dispensing amount adjustment unit configured to communicate with the nozzle opening, be provided in a flow path through which the plasticized material flows, and adjust a dispensing amount of the plasticized material from the nozzle opening by changing an area of an opening formed in the flow path; a pressure adjustment unit configured to adjust pressure of the flow path through a branch flow path coupled to the flow path between the dispensing amount adjustment unit and the nozzle opening; and a control unit configured to control the dispensing amount adjustment unit and the pressure adjustment unit. When the control unit changes the dispensing amount from a first dispensing amount to a second dispensing amount, the control unit controls the dispensing amount adjustment unit to change the area of the opening, and then controls the pressure adjustment unit to adjust the pressure of the flow path. The second dispensing amount is a dispensing amount when the plasticized material is dispensed from the nozzle opening.
