PURPOSE: A sensor target for correction being utilized for a distance measuring device using a capacitive displacement sensor is provided to compensate or eliminate errors caused by tilts of a sensor and a target because a sensor target for correction of a capacitive displacement sensor can be constituted with a simple structure. CONSTITUTION: A sensor target(1) for correction being utilized for a distance measuring device using a capacitive displacement sensor(10) comprises an insulating layer(30) and metal layers(20,40). The insulating layer comprises first and second planes. The first plane is formed by being spaced from a capacitive displacement sensor at a predetermined distance. The second plane is formed by being parallel to the first plane in an opposite side of the first plane. The metal layers are welded to the second plane to be parallel to the insulation layer.
