Provided is a thermal insulator which can be prevented from having gaps. The thermal insulator includes a nonwoven fabric, and xerogel in interior spaces of the nonwoven fabric. The thermal insulator has a plurality of protrusions on a surface of the thermal insulator, a height of the protrusion ranges from 0.10to 0.25inclusive and a size of the protrusion at the surface of the thermal insulator ranges from t to 5inclusive, where t is a thickness of the thermal insulator, and pores are provided inside the thermal insulator in a region provided with the protrusions.

Thermal insulator and method for manufacturing same

An aerogel structure body includes a composite layer containing fibrous materials and aerogel, the aerogel being held between the fibrous materials, and an aerogel layer having a first surface on at least one surface of the composite layer and formed of the aerogel, in which the aerogel layer having a second surface opposite to the first surface, the second surface including a projection portion projecting from the second surface, and a density of the aerogel in the projection portion is 0.1% to 3.0% higher than a density of the aerogel in the aerogel layer (flat portion) other than the projection portion. Therefore, the aerogel structure body that is excellent in dimensional stability and heat insulating properties and that can be manufactured with high productivity and a method of manufacturing the same are provided.
