To provide a non-destructive inspection method, a non-destructive inspection device, and a flexible member that are capable of preventing a distance measurement wheel of a non-destructive inspection device from irregularly rotating, even when an inspection object part has unevenness.SOLUTION: A non-destructive inspection method non-destructively inspects the inside of a wall 51 by movement of a non-destructive inspection device 1 along the wall 51 in a state where a sensor part 11a of the non-destructive inspection device 1 faces the wall 51. The method: disposes a deformable flexible member 3 between the non-destructive inspection device 1 and the wall 51; brings a distance measurement wheel 13 attached to the non-destructive inspection device 1 into contact with the flexible member 3; and rotates the distance measurement wheel 13 by the movement.SELECTED DRAWING: Figure 1 【課題】検査対象部に凹凸が存在する場合でも、非破壊検査装置の距離計測輪の回転が不規則になるのを抑制できる非破壊検査方法、非破壊検査装置および柔軟部材を提供する。【解決手段】この非破壊検査方法は、壁部５１に非破壊検査装置１のセンサー部１１ａを向けた状態で、当該非破壊検査装置１を上記壁部５１に沿って移動させることで当該壁部５１の内側を非破壊で検査する非破壊検査方法であって、上記壁部５１との間に変形可能な柔軟部材３を介在させ、当該柔軟部材３に上記非破壊検査装置１に装着されている距離計測輪１３を接触させて上記移動により上記距離計測輪１３を回転させる。【選択図】図１
