PROBLEM TO BE SOLVED: To provide a load-applied electric resistance measurement testing machine for evaluating new material characteristics by measuring the relationship between the amount of push-in and electric resistance, and a hardness- testing machine with a load-applied electric resistance measurement function. SOLUTION: The testing machine is provided with a conductive penetrate 22 that is conductive and applies a load to a sample(s) that is placed at a sample stand 21, a means 23 for measuring the amount of push-in such as a displacement meter for measuring the change in the amount of push-in when the above conductive penetrator presses the sample, and an electric resistance measurement means 27 such as a milli-ohmmeter that is connected the above sample or the above stand and measures the change in the electric resistance value of the sample when the above conductive penetrator presses the sample, thus performing a specific analysis based on the amount-of-push-in data being measured by the above amount-of-pus-in measurement means an the electric resistance value data being measured by the above electric resistance measurement means.
