PROBLEM TO BE SOLVED: To provide a gas removing element capable of removing a gaseous contaminant sufficiently and cheap in cost.SOLUTION: A gas removing element of the invention has a structure, in which a solid electrolyte is sandwiched between two active carbon fiber layers having no mutual contact. The BET specific surface area of the active carbon fibers forming said active carbon fiber layers has a BET specific surface area of 1000 to 2000 m/g, and said solid electrolyte is a hydrogen ion conductive resin.SELECTED DRAWING: None【課題】ガス状汚染物質を十分に除去することができ、かつ、コストが安いガス除去素子を提供する。【解決手段】本発明に係るガス除去素子は、固体電解質が互いに接することのない２つの活性炭素繊維層に挟まれた構造を有し、前記活性炭素繊維層を成す活性炭素繊維のＢＥＴ比表面積が１０００～２０００ｍ２／ｇであり、かつ、前記固体電解質が水素イオン伝導性樹脂である。【選択図】なし
