In order to provide a powder coating composition containing a flake pigment attaining excellent recyclability and coating property as well as improved metallic feel, brilliance, and brightness of a coating film, the powder coating composition contains powder coating particles including thermosetting resin powder, an adhesive binder, and a flake pigment bound to a surface of the thermosetting resin powder by means of the binder. An average particle size of the powder coating particle is not larger than 100 .mu.m based on D50 conversion, and a bonding ratio between the thermosetting resin powder and the flake pigment is in a range from 90% to 100%.
