The invention provides a hardness tester and a hardness testing method of the hardness tester, which can rapidly carry out hardness tests. The hardness tester is provided with an equation operation part (83) which operates the equation on the surface of a test piece based on the Z-coordinate value of three positions obtained by the focusing of the three different positions on the surface of the test piece carried by a carrying platform, a storage part (81) which stores the equation on the surface of the test piece, a Z-coordinate operation part (84) which operates the Z-coordinate position of the test position on the surface of the test piece based on the equation on the surface of the test piece, and movement mechanism which moves the carrying platform in the Z direction based on the Z-coordinate position on the surface of the test piece. |
