<P>PROBLEM TO BE SOLVED: To provide an insulation storage that can resist high temperature, and has a configuration in which an internal capacity is large with respect to an external dimension. <P>SOLUTION: A data recording unit (the insulation storage) includes a porous heat-insulation material and a sheet-shaped heat-insulation material 52. The porous heat-insulation material has a property of contracting when being heated, and is arranged at an outside of an accommodation space. The sheet-shaped heat-insulation material 52 has a property of expanding when being heated, and is arranged to protect the porous heat-insulation material from heat. Further, the sheet-shaped heat-insulation material 52 expands to fill in a gap caused by the contraction of the porous heat-insulation material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
