A thermal insulation window according to the present invention includes a pair of panels, a space between the panels, a thermal insulation material to fill the space with; and a mechanism capable of filling the space with the thermal insulation material and removing the thermal insulation material from the space. The thermal insulation material is characterized by being made of aerogel, which has a three-dimensional network structure whose framework is formed by a cluster, an aggregation of primary particles, and containing fine particles which have a three-dimensional network structure whose framework is formed by the primary particles. Such a thermal insulation material has extremely high fluidity and can be moved by the liquid, enabling filling it into and removing it from the space between a pair of panels. The thermal insulation member according to the present invention includes a shape-changing cavity and a thermal insulation material to be accommodated in the cavity. The thermal insulation material is a powder, is flowable, has volume retention performance where the volume is retained before and after the change in cavity shape, and moves within the cavity as the cavity shape is changed.
