In paper I, an atmospheric corrosion of metals as Ag, Cu, Zn, etc. was studied by the reflectance of red light or blue light.<BR>The phenomenon that the break point of elongation of rubber depend on an atmospheric corrosion of metals or atmospheric pollution is applied to in this work. The ratio of the break point of elongation of exposed rubber to the break point of elongation of unexposed rubber was calculated for all samples at 3 zones. The relative coefficient between this ratio and each reflectance of metals was calculated by each zone. The phenomena that this ratio depended on RR<SUB>Cu</SUB> (reflectance of copper to red light) and RB<SUB>Zn</SUB> (reflectance of zinc to blue light) were found out.<BR>From these phenomena, we could deduce that an atmospheric pollutant induced these phenomena was oxidant or oxygen because Cu<SUB>2</SUB>O holds 630 mμ resonance and ZnO holds 390 mμ resonance.
