This can be sufficiently avoided, and furthermore, collapse due to external pressure can be sufficiently suppressed. Furthermore, since the inorganic fiber cloth composited with the metal material is lightweight, the entire vacuum container can be made lightweight, making it convenient to move, for example, an analysis sample while maintaining it in a vacuum state.
