<P>PROBLEM TO BE SOLVED: To provide a heat insulation sheet capable of well suppressing or delaying the heat generated at one member such as an electronic component from being transmitted to the other member such as a case incorporating the electronic component, as well as a case which utilizes the heat insulation sheet, by utilizing a latent heat micro capsule including a latent heat storing material having no foaming characteristics. <P>SOLUTION: The heat insulation sheet 1 is constituted by packing a base material 3 of silicone rubber with a latent heat micro capsule 5 including paraffin and a foaming micro capsule 7, not foamed yet but having foaming characteristics (A). When an electronic component arranged on one side of the heat insulation sheet 1 overheats, the foaming micro capsule 7 foams to exhibit heat insulation characteristics as in (B), while the heat passing through the base material 3 is absorbed into the latent heat micro capsule 5 as latent heat. <P>COPYRIGHT: (C)2009,JPO&INPIT |
