Zusammenfassung:	To provide an alkali metal ion detection sensor that can detect alkali metal ions including radioactive cesium ions in a wider range.SOLUTION: The alkali metal ion detection sensor includes a source electrode 14, a drain electrode 15, and a channel layer 18 arranged between the source electrode 14 and the drain electrode 15. The channel layer 18 is covered with a lipid member at least partially, and the lipid membrane and the compound having a capturing group which captures alkali metal ions are combined by siloxane bond.SELECTED DRAWING: Figure 1 【課題】放射性セシウムイオンを含むアルカリ金属イオンを広い濃度範囲で検出できるアルカリ金属イオン検出センサーを提供する。【解決手段】ソース電極１４、ドレイン電極１５、及びソース電極１４とドレイン電極１５との間に配置されたチャネル層１８を有し、チャネル層１８は、少なくとも一部が脂質膜で被覆されていて、前記脂質膜と、アルカリ金属イオンを捕捉する捕捉基を有する化合物とがシロキサン結合を介して結合している、アルカリ金属イオン検出センサー。【選択図】図１
