A heat-insulating container having a first fiber layer (111) with a prescribed density and a second fiber layer (112) which is formed inside the first fiber layer (111) and has a lower density than the first fiber layer (111). The first fiber layer (111) is 0.2 to 1 mm thick, and the second fiber layer (112) is 0.4 to 3 mm thick, with the total thickness of the first fiber layer (111) and the second fiber layer (112) being 0.6 to 4 mm <IMAGE>
