A scratch testing apparatus for performing a scratching test while gradually increasing or decreasing a load, in which a pressure applied to the surface of a test specimen gradually increases or decreases as a head unit, to which a tip is attached, moves horizontally. The scratching testing apparatus includes a head unit having a bottom to which a tip attached; a guiding unit for guiding the head unit to move horizontally; and a pressure changing unit for changing pressure applied to the tip while the head unit is moving along the guiding unit. Therefore, the scratch testing apparatus may perform a scratching test as gradually increasing or gradually decreasing a load applied to the test specimen by the tip by moving the head unit, to which the tip is attached, horizontally.
