PROBLEM TO BE SOLVED: To provide a liquid pouring connector capable of being manufactured by an easier method, and a method for manufacturing the connector.SOLUTION: A detention needle connector 5 as a liquid pouring connector comprises: a body 51 having an internal space 52 and a seal member 53 for sealing the internal space 52 of the body 51 thereby to insert a needle tube. When the detection needle connector 5 is manufactured, the body 51 is formed by a plastic resin injection molding, and the seal member 53 is molded by an insert molding using a liquid silicone rubber self-adhesive material.COPYRIGHT: (C)2016,JPO&INPIT【課題】より簡易な方法で製造可能な投液用コネクタ及びその製造方法の提供【解決手段】投液用コネクタとしての留置針用コネクタ5は、内部空間52を有する本体51と、本体51の内部空間52を封止し、針管を挿通させるためのシール部材53と、を備える。留置針用コネクタ5を製造する際には、可塑性樹脂射出成形により本体51を形成し、液状シリコーンゴム自己接着性材料を用いたインサート成形によりシール部材53を成形する。【選択図】図2
