Abstract
A hardness tester has a test force applier generating a test force using an electromagnetic force generated by supplying a current to a drive coil provided in a magnetic field and applies the test force to an indenter to press the indenter into a surface of a sample; a temperature detector detecting a temperature of the test force applier; and a test force corrector correcting the test force generated from the test force applier based on the temperature detected by the temperature detector.
