The present invention relates to a cinerary urn and, more particularly, to a cinerary urn in which a double vacuum space for ashes or bone dust is provided so that the vacuum state can be maintained despite an external shock and the passage of time, a device for providing the vacuum state has the form of a simple lid for cost reduction and damage prevention, and biscuit-fired red clay excellent in moisture absorption is used inside the inner ashes container while an ABS resin is used outside so that the vacuum state can be maintained. The double vacuum cinerary urn according to the present invention has the following effects. Outer moisture flow through a cinerary urn gap is double-blocked and the ABS resin is used in the outer layer of the inner ashes container while the biscuit-fired red clay is used in the inner layer so that moisture cannot flow in through any part other than the cover. Even if a small amount of moisture flows in, it is absorbed by the biscuit-fired red clay layer, and thus the ashes or the bone dust can be protected from deterioration. The vacuum lid for the cover has a simple and reliable structure, and thus can prevent the inflow of the outside air and moisture and maintain the internal vacuum state. Accordingly, the double vacuum state can be produced and maintained at a low cost and without any complex device. In addition, the cinerary urn can block air and moisture from the inner ashes container of the urn on its own, and thus the installation cost for large facilities such as a thermohygrostat and an air conditioner for heating and cooling equipped outside for ashes deterioration prevention can be minimized while the occurrence of operating costs for such facilities can be minimized.본 발명은 유골함에 관한 것으로, 더욱 상세하게는 유골 또는 골분을 담아두는 공간의 진공 상태를 외부의 충격과 시간의 흐름에도 불구하고 진공 상태가 유지될 확률이 높아질 수 있도록 이중으로 진공 공간을 만들고, 진공 상태를 만들기 위한 장치를 복잡하지 않고 간단한 마개 형태로 만들어서 비용을 줄이고 손상 가능성을 줄였으며, 내부 유골용기의 재질도 흡습성이 뛰어난 초벌구이 황토를 안쪽 재질로 삼고 진공 상태가 유지될 수 있도록 외부 재질은 ABS수지로 만든 유골함
