  • Publication number: 20210115622
    Abstract: Fiber sheets each including internal pores therein are prepared. A fibrous body including the fiber sheets is formed by stacking the fiber sheets and joining the fiber sheets to each other at joining regions. Silica xerogel is put into the internal pores of each of the fiber sheets of the fibrous body by impregnation. The put silica xerogel is hydrophobized while a space is formed between the fiber sheets in a non-joining region between the joining regions of the fibrous body. This method provides a heat-insulating device resistant to a force in surface directions and having a predetermined thickness.
