The present invention relates to polishing slurry and polishing method used for polishing in a process for forming wirings of a semiconductor device, and the like. There are provided polishing slurry giving a polished surface having high flatness even if the polished surface is made of two or more substances, and further, capable of suppressing metal residue and scratches after polishing, and a method of chemical mechanical polishing using this. The polishing slurry of the present invention is polishing slurry containing at least one of a surfactant and an organic solvent, and a metal oxide dissolving agent and water, or polishing slurry containing water and abrasive of which surface has been modified with an alkyl group, and preferably, it further contains a metal oxidizer, water-soluble polymer, and metal inhibitor.
