PROBLEM TO BE SOLVED: To provide a structure having a heat insulation part thereinside, in which deformation and/or crack at a connection part with a support body does not occur even when exposed to significant temperature change.SOLUTION: In a structure 10 having a heat insulation part 13 inside, a heat expansion coefficient of a member 11 forming a portion held between the heat insulation part 13 and a surface exposed to significant temperature change in use of the structure 10 is made smaller than a heat expansion coefficient of a portion 12 other than the above portion of the structure 10.SELECTED DRAWING: Figure 1 |
