Measurements of the thermal conductivity and specific heat of nanofluid of carbon black were performed at room temperature. The transient hot-wire method using parylene-coated Pt wires was employed for measurement of thermal conductivity. The thermal insulation method was employed for measurement of specific heat. The present paper shows these properties of base fluid (aqueous solution of 2.5 w% polyvinylpyrrolidone) and carbon black nanofluid (nanoparticle concentration of 5.0 w%). As a result of experiment, thermal conductivity of the nanofluid is higher than that of the base fluid because it is expected that thermal conductivity of carbon black is higher than that of water. However specific heat of the carbon black nanofluid is lower because it is expected that specific heat of carbon black is lower than that of water.
