An epoxy resin powder coating material is provided, by which, while workability and coating property are not deteriorated, a coating film having excellent heat cycle resistance can be formed also on recent metal parts having a configuration of intricately combining a plurality of different kinds of metals of different material qualities and required to have high-standard performance. The epoxy resin powder coating material is manufactured by blending a spherical inorganic particle and acryl-based core shell type particle having an average particle diameter of 16 to 50 μm in a bisphenol A-type epoxy resin, wherein an average particle diameter of the acryl-based core shell type particle is preferably 0.1 to 0.4 μm.
