To provide a chemiluminescence NOx concentration measurement device capable of accurately measuring an NOx concentration.SOLUTION: A chemiluminescence NOx concentration measurement device measures an NOx concentration by detecting with a detector 3, emission intensity generated when ozone generated by a silent discharge ozone generator 7 reacts with NO in a sample gas in a reaction vessel 2. A replaceable filter is arranged in the middle of a pipe connecting the silent discharge ozone generator 7 with the reaction vessel 2.SELECTED DRAWING: Figure 1 【課題】正確にＮＯｘ濃度を測定することができる化学発光式ＮＯｘ濃度測定装置を提供する。【解決手段】無声放電式オゾン発生器７で生成したオゾンと試料ガス中のＮＯが反応槽２内で反応した際に生じる発光強度を検出器３で検出してＮＯｘ濃度を測定する化学発光式ＮＯｘ濃度測定装置で、無声放電式オゾン発生器７と反応槽２とを接続する配管の途中に交換式フィルタを配置した。【選択図】図１
