It is an object of the present invention to provide a polishing method, with which a surface of high flatness can be obtained without fail at a high removal rate and in a stable manner. The polishing method is to polish a surface to be polished of an object to be polished by using a polishing pad while existing an aqueous chemical mechanical polishing solution containing an oxidizing agent such as hydrogen peroxide between polishing surface of the polishing pad equipped with a polishing part that contains abrasive, and the surface to be polished to be polished of the object to be polished. The aqueous chemical mechanical polishing solution may be contained a heterocyclic compound, a multivalent metal ion, an organic acid and the like. Also, the aqueous chemical mechanical solution may be contained no abrasive.
