<P>PROBLEM TO BE SOLVED: To provide a heat insulating structure which can be used, for example, to reduce cooling loss of an engine. <P>SOLUTION: In the heat insulating structure, the surface of a metal base material 11 is covered with a porous substance 12, and the surface of the porous substance 12 is covered with a coating 13. The metal of the metal base material 11 is impregnated and solidified in small pores of the porous substance 12 in the metal base material 11 side of the porous substance 12. On the coating 13 side of the porous substance 12, the coating bites into the small pores of the porous substance 12. An area of the porous substance 12 between the part of the impregnated and solidified metal on the metal base material 11 side and the coating-bitten part of the coating 13 side serves as a heat insulating space. <P>COPYRIGHT: (C)2012,JPO&INPIT |
