PROBLEM TO BE SOLVED: To provide a latent heat utilizing heat storage insulating material which demonstrates its heat insulating function by storing heat energy in a heat storage material at a high temperature, and by discharging this stored heat energy when the temperature is decreased. SOLUTION: Three kinds of micro capsules, which are the first to the third microcapsules 11, 12, and 13 containing heat storage materials which have different fusion points are applied to the surface of an interior material 14. The first and second microcapsules 11 and 12 are organic type heat storage materials which have a resin-coated surface to form a surface layer. The third microcapsule 13 is Polyacrylic Acid Soda which has absorbed water. The grain diameter of the micro capsule should be 5 to 500 μm. |
