The present disclosure uses a surface property measuring device that includes an arm swingably supported so as to displace a stylus vertically, and an arm lifter that holds the stylus at a predetermined height by rotating the arm. After arranging the arm lifter in a state where the arm can be held at a lower limit height that is only a predetermined drop amount below a predetermined measurement height, the arm is arranged at the measurement height and the stylus contacts a measured object, and in this state surface properties of the measured object are measured.
