An object of the present invention is to provide a probe microscope that permits qualitative and quantitative evaluation on ions existing near the surface of a sample and permits to detect further simply and easily such as impurities, flaws and corrosion origins existing on the sample in high sensitivity. A probe microscope according to the present invention is provided with a test cell that holds a sample and permits to receive liquid, a probe, a counter electrode, a reference electrode, a drive mechanism that causes the probe to follow the surface of the sample as well as to scan the same, a potential control portion that controls a potential between the probe and the reference electrode and a current measuring portion that measures a current flowing between the probe and the counter electrode, and is characterized in that the material of the probe is constituted by a conductive body containing any of gold or gold alloy, carbon or carbon compound, boron, zinc, lead, tin and mercury.
