The purpose of the present invention is to provide a scalp cooling device that can conform to the shape of the head of a patient without having to introduce a liquid or gel or other material and without impeding heat transfer with the scalp, thereby improving heat transfer with the scalp. The scalp cooling device is placed over the head of a user, cools the scalp, and is provided with a cooling cap and an inner cap (17) placed inside the cooling cap. A coolant passage is formed inside the cooling cap, and the cooling cap cools the scalp by means of a coolant flowing through the coolant passage. The inner cap (17) includes a non-woven fabric layer formed using non-woven fabrics, and the non-woven fabric layer is a water-absorbing layer made of resin fiber materials with a high rate of water absorption.於頭皮冷卻裝置中，為使與頭皮間的熱傳導不受到妨礙，不需充填液體或膠體而能夠適合患者的頭部形狀，提高與頭皮的熱傳導性。本發明係提供裝著於使用者的頭部，冷卻頭皮的頭皮冷卻裝置，包含有一冷卻罩及一內罩17，該冷卻罩內部形成有冷媒流路，透過將冷媒流通於冷媒流路中乙冷卻頭皮，該內罩17係裝著於該冷卻罩的內側，包含有不織布所形成的一不織布層，該不織布層係以高吸水性樹脂纖維材質所製成的吸水層。
