PURPOSE: An aromatic heating pack is provided to reduce a manufacturing cost dramatically by using powder or liquid natural aroma component instead of an aroma capsule. CONSTITUTION: An aromatic heating pack is prepared by an exothermic composition including iron, activated charcoal, salt type, water, and hygroscopic agent, and fragrance material for aroma packaged in an envelope having multiple vents and sealed. The iron, activated charcoal, and fragrance material are prepared in powder with no moisture, and the hygroscopic agent includes salt to control salinity for avoiding the contact with moisture with the fragrance material to maintain the fragrance material in powder before opening the sealed package. After the sealed package is opened, the moisture included in the hygroscopic agent is absorbed to the fragrance material and the moisture and the fragrance material is evaporated by the heat generated from the exothermic composition.
