To provide a liquid quantitative discharge device capable of forming a thin potting layer of liquid in a fluidized or semi-fluidized state.SOLUTION: A liquid quantitative discharge device 1 for quantitatively discharging liquid comprises: a nozzle 6 having a discharge port 6a for discharging liquid in a fluidized or semi-fluidized state; a liquid chamber 50 feeding the liquid to the nozzle; a valve 9 reciprocatable to the nozzle in the liquid chamber; and a valve seat 10 disposed between the nozzle and the liquid chamber and having a through hole 10a communicating the nozzle and the liquid chamber. A recess 10b is provided around the through-hole, and a space is formed between a valve tip and the bottommost part of the recess when the valve tip comes into contact with the valve seat.SELECTED DRAWING: Figure 1 【課題】流動体状または半流動体状の液体を薄くポッティングすることができる液体定量吐出装置を提供する。【解決手段】液体定量吐出装置１は、液体を定量的に吐出させる装置であって、流動体状または半流動体状の液体を吐出する吐出口６ａを有するノズル６と、ノズルに液体を供給する液室５０と、液室内をノズルに対して往復動可能なバルブ９と、ノズルと液室との間に配置されており、ノズルの吐出口と液室との間を連通する貫通孔１０ａを有するバルブシート１０とを備え、バルブシートは、貫通孔の周囲に凹部１０ｂが設けられており、バルブの先端部がバルブシートに当接したとき、バルブの先端部と凹部の最底部との間に空間が形成される。【選択図】図１
