Abstract
A production method of an indentation curve is given, in which when an indentation curve showing a relationship between indentation force and indentation depth in a process of indenting an indenter into a surface of a sample is produced, a measurement range using an (i−n)th (here, i and n are natural numbers) measurement value as a reference is provided, and the indentation depth or indentation force is temporarily measured when the indentation force or indentation depth is gradually changed, respectively, and when a temporarily measurement value obtained by the temporarily measurement is out of the determination range, indentation depth at the relevant indentation force or indentation force at the relevant indentation depth is measured and set as an ith measurement value, or the temporarily measurement value is used as the ith measurement value.
