To provide a bone storage container aimed at quickly sedimenting in a water when a canvas storage container is dropped into water, water collapse and biodegradation in water for a long time, and going back to nature together with bone .SOLUTION: A laminated material composed of pulp is accumulated with a biodegradable adhesive and it is used as a laminated press board. This laminated press board is cut out, two hemispherical parts are formed with a trimmer, cylindrical holes are drilled in the bottom of each to form the constituent parts 5a, 5b. A ceramic container 6 is inserted into one of the component parts 5 b and a component 5 a of the other constitution is further inserted to obtain a remains container having a total specific gravity of 1 or more.(FIG.【課題】遺骨収納容器を水中に投下する際に、水中に迅速に沈降させ、さらに水中で長い間に水崩壊、生分解してなくなり骨共々自然に帰ることを目的にした遺骨収納容器を提供する。【解決手段】パルプからなる集成材を、生分解性接着剤で集積の上、積層プレスボードとする。この積層プレスボードを切り出し、トリマーで2つの半球形の部品を形成し、各々の底面に円柱状の穴を掘り、構成の部品5a、5bとする。構成の部品の一方5bに、陶製の筒6を差し込み、更に他方の構成の部品5aを差し込み、全体の比重が1以上である遺骨収納容器とする。【選択図】図3
