To provide a discharge product capable of obtaining a finely foamy discharged material by discharging a foamable composition using compressed gas, without using a complicated structure.SOLUTION: A foam discharge nozzle used by being attached to a discharge container filled with a foamable composition composed of compressed gas and a stock solution containing a foaming agent comprises a body part, and a nozzle part provided with a discharge opening for discharging the foamable composition. The body part is provided with a first passage. The nozzle part is provided with a second passage communicating with the first passage, the nozzle part comprising a throttle part and a taper part. A diameter of the second passage at the throttle part is smaller than a diameter of the first passage. A diameter of the second passage at the taper part is enlarged in a taper shape from the diameter of the second passage at the throttle part so as to be the second passage at the discharge opening.SELECTED DRAWING: Figure 1 【課題】複雑な構造を用いずに、圧縮ガスを用いた発泡性組成物を吐出し、きめ細かな泡状の吐出物を得ることのできる吐出製品を提供する。【解決手段】起泡剤を含む原液および圧縮ガスからなる発泡性組成物が充填された吐出容器に取り付けて使用され、本体部と、発泡性組成物が吐出される吐出孔が形成されたノズル部とを備え、本体部は、第１通路が形成されており、ノズル部は、第１通路と連通する第２通路が形成されており、絞り部と、テーパ部とを有し、絞り部における第２通路の径は、第１通路の径よりも小さく、テーパ部における第２通路の径は、絞り部における第２通路の径から、吐出孔における第２通路の径となるようテーパ状に拡径されている、発泡吐出ノズル。【選択図】図１
