PROBLEM TO BE SOLVED: To provide a heat insulating material which can suppress breakage, peeling of powder particles or the like which is caused in processing, transportation, attachment or the like without using a special coating material or binder, and is excellent in both flexibility and heat-insulating property, and a method for manufacturing the same. SOLUTION: The high-performance heat insulating material includes a heat-insulating cover layer 2 with low heat conductivity, which is provided on one surface side of a sheet-like fiber molding 1. The bulk density of the fiber molding 1 is 64-160 kg/m<SP>3</SP>. The heat-insulating cover layer 2 includes a powder selected from silica powder, alumina powder and aluminum silicate powder and a powder of heat reflecting function material. An coating layer of a solution including 2, 4, 6-triisopropyl-1, 3, 5-trioxane and paraffin-based hydrocarbon can be provided on the surface of the heat-insulating cover layer 2.
