A plasma processing apparatus includes a cylindrical chamber defining a processing space in which a substrate is processed, and a member constituting an outer circumference of the cylindrical chamber. The member includes at least one flow path inlet configured to allow a heat transfer medium to flow in therethrough, at least one flow path outlet configured to allow the heat transfer medium to flow out therethrough, at least one flow path connecting the flow path inlet and the flow path outlet to one another to allow the heat transfer medium to flow therethrough, and at least one folded-back portion formed in the flow path. The flow path inlet and the flow path outlet are located close to each other, and the flow path is formed at a specific angle in a circumferential direction of the member.
