A hardness tester enabling a user to form an indentation in a desired test position, capable of performing an accurate hardness test even when center positions of an indenter and a field lens are offset. The hardness tester includes an XY stage displacing a sample stage in a horizontal direction; a CCD camera capturing images of a sample surface via a field lens; a monitor displaying the images; a turret capable of selectively positioning the indenter or the field lens in a predetermined position opposite the sample; a memory storing an amount of horizontal direction offset between the center positions of the indenter and the field lens when positioned in the predetermined position; and a CPU displaying, based on the amount of offset stored in the memory, a mark indicating the center position of the indenter on the monitor when the field lens is positioned in the predetermined position.
