Abstract: 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.

Abstract: A hardness tester capable of facilitating positioning of a sample even when the hardness tester includes a manual XY stage. The hardness tester includes an XY stage displacing a sample stage in a horizontal direction; a CCD camera capturing an image of a sample surface via an objective lens; a monitor displaying the image of the sample surface captured by the CCD camera; an operator specifying a test position at which an indentation is to be formed, the test position being specified on the image displayed on the display; and a CPU calculating, in conjunction with displacement of the XY stage, an amount of offset in the XY direction between the test position and a center position of the indenter when forming the indentation, then displaying the calculated amount of offset on the display.
