To provide an injector capable of effectively preventing dripping, and efficiently performing injection when performing injection repeatedly.MEANS: An injector comprises: a positive displacement reciprocating pump having a cylinder that stores liquid and has an ejection hole at its tip, and a plunger; and a drive device that causes the plunger to perform push-out and retraction operations. The drive device causes the plunger to perform the push-out operation by a predetermined distance (X1), and then causes the plunger to perform the retraction operation by a distance (X2) that is smaller than the predetermined distance (X1).SELECTED DRAWING: Figure 4 【課題】液垂れを効果的に防止し、且つ、繰り返して噴出を行う場合に効率的に噴射をおこなうことができる噴射装置を提供すること。【手段】液体を貯留し先端に噴出孔が形成されたシリンダと、プランジャとを、有する容積式の往復ポンプと、前記プランジャに押出し動作及び引込み動作をさせる駆動装置と、を備えた噴射装置であって、前記駆動装置は、前記プランジャに所定距離（Ｘ１）だけ前記押出し動作をさせた後、前記プランジャに前記所定距離（Ｘ１）よりも小さい距離（Ｘ２）だけ引込み動作をさせる。【選択図】図４
