PROBLEM TO BE SOLVED: To provide a method for producing a hard tissue-dissolved material, capable of preparing the material by dissolving a hard tissue in acid and/or specified enzymes so that components contained in the hard tissue, for example, in a bony tissue, are prevented from losing physiological activity inherent in the components. SOLUTION: This method for producing the hard tissue-dissolved material comprises a pulverizing process S1 where the hard tissue is pulverized while it is cooled at 0C to -250C, a dissolving process S2 where the pu |
