The purpose of the present invention is to provide a configuration, in a discharge part to be used in a discharge container, wherein sealing properties that make it possible to prevent contamination of a contained fluid being accommodated are realized, and a reduction in manufacturing costs can be effectively achieved. A discharge part (17) to be used in an eyedrop container (10) is provided with: a valve (30) configured from an elastic material and having a vertically elongated shape, the valve (30) having formed in the interior thereof a space (31) through which a contained liquid (100) passes, and having formed on the distal end thereof a slit (32) that reaches the space (31) from the exterior； and an orifice (20) inserted from the proximal-end side of the space (31), the orifice (20) having a portion formed such that the outer diameter thereof is greater than the inner diameter of the space (31). The proximal-end side of the valve (30) expands from the space (31) side due to the orifice (20), whereby a force is applied to the distal-end side of the valve along the direction in which the slit (32) is closed.本發明提供一種用於吐出容器之吐出部中，實現可防止所收容之內容液受污染之密閉性，並且可達成製造成本之有效降低的構成。用於點眼容器10之吐出部17，具備：閥30，其由具有彈性之材料構成為縱長，於其內部形成有供內容液100通過之空間31，並且於其前端形成有自外側到達空間31之狹縫32；以及孔口20，係自空間31之基端側嵌入，具有其外徑形成較空間31之內徑大之部分。藉由該孔口20而將閥30之基端側自空間31側擴幅，藉此將狹縫32閉合之方向之力作用於閥30之前端側。
