PROBLEM TO BE SOLVED: To provide a dispenser and a dispenser unit capable of discharging a liquid of high viscosity and to provide a three-dimensional shaping device using the same.SOLUTION: The dispenser includes: a high-pressure liquid supply part which supplies a high-pressure liquid of pressure higher than atmospheric pressure; a discharge part which discharges the high-pressure liquid supplied from the high-pressure liquid supply part; and a driving source which drives the discharge part. The discharge part includes: a rotary rotor rotated by the driving source, which has at least one housing part for housing the high-pressure liquid formed in an outer peripheral surface; a casing for housing the rotary rotor in a rotatable state, in which a liquid supply passage for communicating the housing part with the high-pressure liquid supply part and a discharge nozzle which communicates the housing part with the outer side of the discharge part are formed; and a control part which controls rotation of the driving source and controls the position of the housing part in the rotating direction.SELECTED DRAWING: Figure 6 【課題】高粘度の液体を吐出することができるディスペンサ、ディスペンサユニット及びこれを用いる立体物造形装置を提供すること。【解決手段】大気圧よりも圧力の高い高圧液体を供給する高圧液体供給部と、高圧液体供給部から供給される高圧液体を吐出する吐出部と、吐出部を駆動させる駆動源と、を有し、吐出部は、外周面に少なくとも１つの高圧液体を収容する収容部が形成され、駆動源によって回転される回転ロータと、回転ロータを回転自在の状態で収容し、収容部と高圧液体供給部とを連通させる液体供給路と、収容部と吐出部の外部とを連通させる吐出ノズルと、が形成されたケーシングと、駆動源の回転を制御し、回転方向における収容部の位置を制御する制御部と、を備える。【選択図】図６
