Ice adhesion often causes the accident accompanied by an economic loss. So, it is important to know real ice adhesion force. Ice adhesion force is often measured by the method that a shearing force is given at the interface between the ice and solid surface. However, the measured value is an apparent ice adhesion force including a force breaking ice. If ice diameter approaches the nano-scale, relative evenness of the solid surface for the ice increases. At that time ice adhesion force without a force breaking ice can be measured. So, in this paper, the adhesion forces of ices with diameters less than 100 nm to the metal test plates are measured by the SPM, the measured values are compared with those measured in the macro-scale.
