A micro-hardness measurement method for calculating the hardness of a test sample by pushing an indenter in the test sample and forming an indentation thereon, including: a loading step for extracting load data showing the relationship between load L applied to the indenter and a depth delta to which the indenter is pushed in from the surface of the test sample; an unloading step of extracting unloading data showing the relationship between the load L applied to the indenter after the load is unloaded and the depth delta; a first step of judging, by comparing the unloading data with the load data, the load fluctuation amount from the maximum depth delta<SUB>0 </SUB>when unloading the load; and a second step of judging the load at the depth delta<SUB>1 </SUB>(delta<SUB>1</SUB><delta<SUB>0</SUB>) when unloading the load or the load fluctuation amount in the vicinity of the depth delta<SUB>1</SUB>.
