PROBLEM TO BE SOLVED: To obtain an economically inexpensive powder coating capable of forming a thin film having a uniform thickness without relying on high-cost mechanical pulverization and hardly causing pinholes. SOLUTION: This powder coating is characterized in that polyamide porous spherical particles having 1-20μm number-average particle diameter and 1.0-1.5 ratio of the volume-average particle diameter to the number-average particle diameter are included as a principal component.
