PROBLEM TO BE SOLVED: To provide a powder coating composition capable of forming a paint film that satisfies both chemical resistance and flexibility in a satisfiable level when applied to inside coating of drum. SOLUTION: The powder coating composition comprises an o-cresol novolac-type resin (A), a bisphenol-A-type epoxy resin (B), and at least one sort of curing agent selected from the group consisting of a phenolic curing agent, amine-based curing agent, hydrazide-based curing agent, and carboxylic acid-based curing agent, and the compounding ratio [(A)/(B):weight ratio] of the o-cresol novolac-type resin (A) and the bisphenol-A-type epoxy resin (B) is 95/5 to 60/40.
