To provide an electric wire coating deterioration detector and an electric wire coating deterioration detection method, capable of securing diagnostic accuracy of deterioration degree including excessive fouling of an electric wire to be tested.SOLUTION: When the deterioration degree of an electric wire 2 to be tested is detected, a deterioration diagnosis unit 12 irradiates a light source 6 with light, and splits the reflected light by a spectroscope 7 to obtain a reflectance of each wavelength. At this time, the deterioration diagnosis unit 12 determines whether or not the electric wire 2 to be tested is excessively fouled, based on the reflectance of 750 nm in a wavelength band not affected by the deterioration. The deterioration diagnosis unit 12 performs deterioration diagnosis on the electric wire 2 that has not been determined to be excessively fouled.SELECTED DRAWING: Figure 1 【課題】検査対象である電線の過汚損を含む劣化度の診断精度確保を可能にした電線被覆劣化検出装置及び電線被覆劣化検出方法を提供する。【解決手段】劣化診断部１２は、検査対象の電線２の劣化度を検出するにあたり、光源６の光を照射し、その反射光を分光器７で分光して各波長の反射率を取得する。このとき、劣化診断部１２は、劣化の影響を受けない波長帯域の７５０ｎｍの反射率を基に、検査対象の電線２が過汚損品であるか否かを判定する。劣化診断部１２は、過汚損品と判定されなかった電線２に対し、劣化診断を実行する。【選択図】図１
