Summary:PROBLEM TO BE SOLVED: To remove oil while suppressing blackening of a protection cover.SOLUTION: A method includes arranging a coil 81 in a periphery of at least a portion of a cylindrical body 41 at the same side as the other end (upper end) of a sensor element 20 with respect to a protection cover 30 to avoid the protection cover 30 of an assembly 15, induction-heating the portion of the cylindrical body 41 where the coil 81 is arranged in the periphery by applying current to the coil 81, and hence removing oil adhering to the portion.SELECTED DRAWING: Figure 4 【課題】油分を除去しつつ保護カバーの黒化を抑制する。【解決手段】組立体１５のうち保護カバー３０を避けるように筒状体４１のうち保護カバー３０よりもセンサ素子２０の他端（上端）と同じ側の少なくとも一部の周囲にコイル８１を配置し、コイル８１に電流を流すことにより筒状体４１のうち周囲にコイル８１が配置された部分を誘導加熱してその部分に付着した油分を除去する。【選択図】図４
