PROBLEM TO BE SOLVED: To appropriately guide a fragrance to a heating vibrating portion and appropriately exhaust air in the fragrance even in a configuration in which a fragrance stored in an upper portion is flowed downward and the fragrance is sprayed by the action of a heating vibrating portion. The present invention is a cartridge device used in a diffuser device, and is a strut portion as a member provided with a storage unit 18 for storing fragrance and a flow path 55 for fragrance communicating with the storage unit 18. It includes a 51, a piezo element as a heating vibration unit 14 provided in the flow path 55, and a water supply core 57 provided in the flow path 55 and one end of which is in contact with the heating vibration unit 14.
