Abstract: An oxide layer thickness measurement device according to the present invention stores, for each of layer thickness measurement sub-ranges constituting a layer thickness measurement range, layer thickness conversion information representing a correlation between a layer thickness and an emitting light luminance where a ratio of a change in the emitting light luminance to a change in the layer thickness in the layer thickness measurement sub-range falls within a set extent. The device includes a plurality of emitting light luminance measurement parts for measuring emitting light luminances of a surface of a steel sheet at respective measurement wavelengths different from each other. Calculated in connection with each of the emitting light luminances of the surface of the steel sheet measured by the emitting light luminance measurement parts are the layer thickness corresponding to the measured emitting light luminance and a ratio at the layer thickness by using the layer thickness conversion information corresponding to each of the emitting light luminance measurement parts. The calculated layer thickness is extracted as a candidate value for an actual thickness layer when the calculated ratio is within the set extent assigned for the layer thickness conversion information.
