Cool feeling when our skin touches the surface of a plate is much less than that with a metal plate. Sometimes in winter, however, one feels very cold when he sits on the convenience seat of a rest room. In the present study, the relation between the cool feeling and the contact area of a plastic, Juracon, was investigated physically and sensuously with changing the contact area by grooving the plastic surface. The physical estimation for the cool feeling was performed with a KES-FB Thermolab II by measuring the maximum heat flux, qmax, obtained at the moment when the heating copper plate touched the plastic plate. Qmax was reduced linearly from 0.36 for 100% contact to 0.08 W/cm^2 for 0% contact. The sensory evaluation of the feeling was performed for the contact of the skin inside the finger top with the plastic surface. It was found that qmax and the feeling have a good correlation for the contact area changing from 100 to 20% of the plastic surface.
