PROBLEM TO BE SOLVED: To provide a functional component supply device capable of stably supplying a functional component.SOLUTION: A supply device (1) of the present invention comprises: a vessel (10) which stores a functional component and is sealable an introduction part (11) arranged in the vessel and communicating with the vessel inside from the vessel outside a leading out part (12) arranged in the vessel and communicating with the vessel outside from the vessel inside and a transmission pipe (13) arranged in the vessel, communicating the leading out part and transmitting the functional component present in the vessel to the inner circumferential surface side from the outer circumferential surface side. The transmission pipe is desirably composed of a silicone resin and a fluororesin. The supply device of the present invention is different from a conventional dynamic head space method, and indirectly supplies the functional component in the vessel to the outside via the transmission pipe. Thus, the supply device of the present invention can stably supply a constant quantity of functional component without causing liquid leakage even when mounted on an automobile having many vibration.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】機能性成分を安定して供給できる機能性成分の供給装置を提供する。【解決手段】本発明の供給装置(1)は、機能性成分を貯留して密閉できる容器(10)と、容器に配設され容器外から容器内へ連通する導入部(11)と、容器に配設され容器内から容器外へ連通する導出部(12)と、容器内に配設され導出部を連通すると共に容器内にある機能性成分を外周面側から内周面側へ透過させる透過管(13)とを備える。透過管は、シリコーン樹脂やフッ素樹脂等からなると好ましい。本発明の供給装置は、従来のダイナミックヘッドスペース法とは異なり、容器内の機能性成分を透過管を介して間接的に外部へ供給する。このため本発明の供給装置は、振動の多い自動車へ搭載されても、液漏れ等を生じずに、一定量の機能性成分を安定的に供給できる。【選択図】図1
