Claims

[Scope of utility model registration request]

A detector is mounted on a roller shaft with an active coil and a dummy coil disposed inside and has rollers at both ends, and the detector faces the object to be measured, which is sent at a constant speed by a feed roller, via the roller shaft. and a measuring device main body that measures an impedance change of an active coil in the detector based on eddy current loss occurring in the feed roller, the roller axis being arranged in a direction perpendicular to the surface of the object to be measured. A thickness gauge characterized in that it is configured to move over the surface of an object to be measured using an axis as a fulcrum.
