A hardness tester 100 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 141 and a field lens 15 are offset. The hardness tester 100 includes an XY stage displacing a sample stage 2 in a horizontal direction; a CCD camera capturing images of a sample surface via a field lens 15; a monitor displaying the images; a turret capable of selectively positioning the indenter 141 or the field lens 15 in a predetermined position opposite the sample S; a memory storing an amount of horizontal direction offset between the center positions of the indenter 141 and the field lens 15 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 141 on the monitor when the field lens 15 is positioned in the predetermined position. |
