[Abstract] The flux of the organic substance for the Osaka Bay sediment was estimated by the analysis of the vertical distribution of organic carbon (OC), organic nitrogen (ON) and total phosphorus (TP) in the sediment core. The profile of these organic substances in the core evaluated the influence of the mixing using the advection-diffusion model, because it was disturbed by the effect of mixed layer in the sediment surface. The decomposition rate of the organic substance in early diagenesis was also estimated. The flux of early decomposable OC, ON and TP loaded on the Osaka Bay sediment from sea water was 3.00mgC, 0.42mgN and 0.068mgP cm^<-2>yr^<-1>, respectively. Then, the decomposition rate of these organic substances that became inorganic in early diagenesis in the upper layer of the core was estimated at 0.0693mgC, 0.0083mgN and 0.0012mgP cm^<-2>yr^<-1>. It is significant to clarify flux and decomposition rate of the organic substance in the sediment concerning organic contamination and eutrophication in the coastal zone of Osaka Bay.
