description A hardness tester forms an indentation on a surface of a sample by loading a predetermined test force with an indenter and measures a hardness of the sample using the indentation. The hardness tester includes a light source emitting light on the surface of the sample and forming an illumination pattern having a spot; and a controller forming the indentation by bringing the indenter into contact with the sample in a state where a perpendicular line of a vertex of the indenter overlaps a test point when the position of the spot of the illumination pattern formed by the light source on the surface of the sample is used as the test point.
