To construct the Sustainable Society, the importance of consideration in the design phase to 3R (Reduce , Reuse , Recycle) increases in various industrial products. Especially, concerning Reuse and Recycle, the improvement of the disassembly property of the products is an indispensable matter. Then, the quantity assessment method of facility disassembly property is examined in this research. The comparison by the disassembly time is effective as the means to evaluate the disassembly property. Then, we develop the Disassembly Property Index which is able to estimate the real disassembly time easily from the data which can be obtained at the design stage. In this paper, the method of deciding each element that composed the index is described, analyzing 32 products' disassembling examination results, and we show effectiveness of the Disassembly Property Index as the assessment tool for estimating the real disassembly time was obtained.
