A composite powder wherein an organic or inorganic core powder is substantially completely covered with one or more types of organic, inorganic, or metallic powders having an average particle size one-fifth or less of the average particle size of the above core powder by means of mixing and compression. The composite powder may be manufactured by mixing and compressing the above core powder and coating powder using a ball mill or other mixer charged with a ball shaped mixing medium of an average diameter of 5 mm or less. This composite powder may be used in, for example, skin treatment agent, makeup type cosmetics, sunburn preventing cosmetics, deodorants.
