PROBLEM TO BE SOLVED: To provide a heating tool which can be used while working and efficiently gives heat to the periphery of an eye to help recovery from eye fatigue or improvement of visual acuity. SOLUTION: The face including both eyes can be covered, an opening is formed at a position corresponding to the eyes, and the periphery of the opening comprises a chamber containing a heat-generating composition that generates heat in the presence of air. A heating body having a main body portion on which a heat generating member is arranged and a mounting portion capable of mounting the main body portion on the face, and a thermal body having a small hole for providing visibility and heating in a state of being fitted into the opening of the main body portion. An eye mask type heater including a covering member protruding from the opening surface of the body.
