A simple method for measuring the thermal conductivity of low-conductive sheet materials such as a sheet of paper has been developed. A 7059 glass plate of 0.7 mm thickness made of CORNING is used as a reference material. An aluminum hot-wire of 10 mm length having rectangular crosssection of 0.5μm in thickness and 10μm in width is formed on the plate by sputtering and the photolithography technique. Seven kinds of thermal transfer paper for word processors are used as samples. A piece of the paper sample covered with a piece of impermeable polyimide tape that prevents moisture movement is put on the wire, another 7059 glass is placed on the paper sample, and a constant weight is loaded on the glass. The measured thermal conductivities of paper samples were from 0.3 to 0.41 W/(m・K). The data acquisition times are about 1.0 s. Errors in the present measurements are checked by the reference material.
