PROBLEM TO BE SOLVED: To provide a technology capable of improving thermal conductivity and keeping insulating properties by mixing a carbon material in a resin molded article. SOLUTION: The resin molded article 10 shown in figure (a) is characterized by that when the article is divided into a skin 14 and an inner part 15, the direction of a carbon nano material 13 is irregular in the inner part 15 but approximately parallel to the surface in the skin 14. Namely, as shown in figure (c), the linear carbon nano material 13 is arranged in all directions in the inner part 15, and as shown in figure (b), the carbon nano material 13 is arranged in parallel to the surface in the skin 14. When the carbon nano material playing a function for lowering the electric resistance value is arranged approximately in parallel to the surface, the electric resistance value in the direction intersecting the surface at right angles, namely, in the thickness direction is increased. Therefore, the skin plays a function for increasing the electric resistance value in the thickness direction, and as a result, insulating properties can be ensured. COPYRIGHT: (C)2006,JPO&NCIPI |
