To provide a cooling tool for cooling a carotid artery part.SOLUTION: The belt portion 2 is attached to a cover portion 1 covering the back of the head to cover the left and right carotid artery portions, and incorporates a planar water-absorbing material. When ice is put in the belt part 2, when cold water of melted ice is immersed in the water absorbent material, the carotid artery is cooled by the heat of its vaporization. In addition, the ice cub keeps the ice cub keeping the planar water absorbing material at the middle position in the vertical direction and the water sink absorbing part of the water absorbing material under the ice cube partition, and absorbs the cold water melted with the ice over time, and unpleasant water To prevent sagging and to make it easier for water absorbing material to absorb chilled water melted with ice by preventing moisture permeation and waterproofing sheet on the outside of the pocket space where ice is placed.(FIG.【課題】頸動脈部を冷却する冷却具を提供する。【解決手段】後頭部を覆うカバー部1に連結して左右の頸動脈部を覆う、面状の吸水材を組み込んだベルト部2を設ける。ベルト部2には氷や保冷剤を入れられるポケットを設けて、氷を入れた場合、溶けた氷の冷水が吸水材に浸され、その気化熱で頸動脈周辺を冷却する。また、面状の吸水材を上下方向の中間位置で設けた氷止め仕切りとその下方に吸水材の水たれ吸収部分を残し、氷が時間とともに溶けた冷水を吸収し、ベルト部から不快な水たれが起きることを防ぐこと、及び、氷を入れるポケット空間の外側を透湿防水シートを設けることにより氷の溶けた冷水が外側に漏れ落ちることなく吸水材に吸収されやすいように構成する。【選択図】図1
