Ice adhesion to a cooling solid surface often causes the serious problems. So, it is important to unravel a mechanism of ice adhesion and prevent it. In past studies, ice adhesion force have been measured in a macro-scale. However, in the case of the metal plate, ice was broken and measured force included the force to breaking ice due to roughness of the metal surface. it was impossible to measure accurately because of breaking the ice. On the other hand, one of authors were developed the measurement method in a nano-scale by Scanning Probe Microscope （SPM） without breaking the ice. In this study, ice adhesion force to copper test plate was measured in a nano-scale using described above. From measurement results of view, oxidation characteristic of the copper test plate was investigated. Exposed the copper surface in the atmosphere and measuring ice adhesion force at various oxidation times, Relationship the oxide layer on the copper surface and ice adhesion force was clarified.
