This study attempted to review the chemical composition of 25 samples of Sangpyeongtongbo having different manufacturing place and period, and then to find the manufacturing method. As a result of chemical composition analysis of Sangpyeongtongbo, main components include Cu, Zn and Pb, and some samples contained Sn and Fe. But, the chemical composition of each Sangpyeongtongbo varied with big differences. When the main content change was examined, Cu and Sn became decreased at the later period, and Zn and Pb had higher contents. The difference in the ingredient content had close relation for the profit of Sangpyeongtongbo. When refined microstructure was observed, 25 kinds of Sangpyeongtongbo had developed different types of microstructure such as dendrite, large grain and grain refinement. But, 25 kinds of Sangpyeongtongbo had no heat treatment processing. And, the types of microstructure were difference, which seems because different microstructure was developed due to the difference of Sn and Fe and cooling speed in Sangpyeongtongbo
