PROBLEM TO BE SOLVED: To provide a heat conductive member obtained by a relatively easy manufacturing method and having anisotropy of heat conductivity, and an engine structure including the heat conductive member.SOLUTION: A heat conductive member 51 is formed into a substantially arc shape or substantially fan shape, and includes a plurality of anisotropic heat transfer pieces 91 of which one radial or circumferential heat conductivity among one in a radial direction, one in a circumferential direction and one in an axial direction vertical to the radial direction and the circumferential direction is smaller than heat conductivities in the residual two directions. The anisotropic heat transfer pieces 91 are arrayed in the circumferential direction so that anisotropic heat transfer pieces 91 adjacent in the circumferential direction are connected to each other, thereby to form cylindrical or columnar anisotropic heat conductive parts 52, 53.SELECTED DRAWING: Figure 4 |
