PROBLEM TO BE SOLVED: To provide polishing media for largely restraining generation of media powder being industrial waste, by providing a stable polishing quantity and superior surface processing when barrel polishing a metallic work. SOLUTION: A diamond abrasive grain 12 having the average particle size falling within a range of 10μm to 200μm is fixed by a plating film 13 to a surface of a core 11 having the average particle size of 1 mm to 20 mm. The core 11 is composed of at least one kind of construction material of WC, TiC, aluminum, titanium or rare earth metal (including yttrium), and a specific gravity of the polishing media 10 is set to 4 or less. When barrel polishing by inputting a polishing liquid suspending these polishing media 10 in a liquid medium and the metallic work in the barrel, due to being extremely low in an abrasion level of the polishing media 10, the stable polishing quantity and the superior surface processing are provided, and generation of media powder being the industrial waste can be largely restrained.
