Provided is a disposable body warmer which suppresses an unpleasant smell from iron powder, exhibits a fragrance effect using a fragrance, and is capable of maintaining stable heat generation. In a storage pouch (1) having air permeability, a heating composition including iron powder, activated carbon (3), salts, a water-absorbing resin, and water, a fragrance (4), and a fragrance adsorption inhibitor (5) that inhibits adsorption of the fragrance (4) to the activated carbon (3) are encapsulated. The fragrance adsorption inhibitor (5) includes a low active substance which has an iodine adsorption capacity lower than that of the activated carbon (3). The low active substance is an activated carbon precursor before an activation process and is preferably material ash.提供一種拋棄式暖暖包,可抑制源自於鐵粉的不舒服臭味,同時可使香料所產生的芳香效果發揮,且可持續穩定的發熱。 一種拋棄式暖暖包,在具有通氣性的收納袋1封入:包含鐵粉、活性碳3、鹽類、吸水性樹脂及水之發熱組成物;香料4以及抑制香料4之吸附於活性碳3之香料吸附抑制劑5。香料吸附抑制劑5包含碘吸附能力比活性碳3低的低活性物質。低活性物質為激活處理前的活性碳前驅物,較佳為襯料。 【代表圖】1‧‧‧拋棄式暖暖包的收納袋2‧‧‧氧3‧‧‧活性碳4‧‧‧香料5‧‧‧香料吸附抑制劑
