The present invention such as by increasing the temperature cold, when lowering the so-called heat generation, bold and (large) beneath the skin of the underarm of the wearer with a cooling device to be used when lowering the temperature by applying a coolant to the vessel, by mounting on the body, providing a cooling device that can be used without any noticeable. A is a cooling device of a temperature at the time of heat generation to lower the body temperature by applying a coolant to the armpit, the substrate 1 having a water absorption, made from the holding portion 2a of the coolant, the substrate 1 It consists length required to hold through Kesagake holding portion 2a is provided with means for holding the substrate a coolant is formed in a cover shape.BACKGROUND 1【課題】風邪などによる体温の上昇、いわゆる発熱を下げるときに、着用者の腋の下の皮膚の下にある太い(大きい)血管に冷却材を当てて体温を下げるとき使う冷却具で、身体に装着して、目立つことなく使える冷却具を提供する。【解決手段】腋の下に冷却材を当てて体温を下げる発熱時の体温の冷却具であり、吸水性を有する基材1と、冷却材の保持部2aからなり、基材1は袈裟懸けにかけて保持するに必要な長さからなり、保持部2aはカバー状に形成され冷却材を基材に保持する手段を備える。【選択図】図1
