To provide a spout which is constructed so as to prevent a layer including barrier resin from being exposed, and has a shape that a rate of defective goods becomes low.SOLUTION: A spout has a spout body which is installed in a container and constructs a discharge opening, and a cylindrical forming body inserted in the spout body. The spout body has a claw portion which locks an end face at a discharge opening side of the cylindrical forming body so as to prevent the cylindrical forming body from coming off from the discharge opening side. The cylindrical forming body has a resin layer I including barrier resin that is an outermost layer or an intermediate layer, and a resin layer II not including the barrier resin that is an innermost layer. The claw portion covers all over the end face of the resin layer I of the end faces of the cylindrical forming body, and locks the end face of the cylindrical forming body so as to cover not all over but partially the resin layer II.SELECTED DRAWING: Figure 1 【課題】バリア性樹脂を含む層が露出しないように構成されたスパウトであって、不良品率が低くなるような形状を有するスパウトを提供することを目的とする。【解決手段】 容器に取り付けられて注出口を構成するスパウト本体と、該スパウト本体に内挿された筒状成形体とを有し、前記スパウト本体が、前記筒状成形体が前記注出口側から抜け出ないように前記筒状成形体の前記注出口側の端面を係止する爪部を有するものであり、前記筒状成形体が、最外層又は中間層であるバリア性樹脂を含む樹脂層Ｉと、最内層であるバリア性樹脂を含まない樹脂層ＩＩとを有するものであり、前記爪部が、前記筒状成形体の端面のうち樹脂層Ｉの端面を全て被覆し、かつ、樹脂層ＩＩの端面の全てを被覆しないよう前記筒状成形体の端面を係止するものである、スパウト。【選択図】図１
