Claim:
1. A heat generating eye mask comprising: a stretch bag that is air-permeable and a heat generating element enclosed in the stretch bag, a length of the stretch bag being greater than a width of the stretch bag, the stretch bag including a first stretch sheet that is to be provided proximal to a wearer and a second stretch sheet that is to be provided distal to the wearer relative to the first stretch sheet of the stretch bag, the heat generating element having a first side which is air-permeable and adapted to be located more proximally to the wearer, a second side which is adapted to be located more distally to the wearer, and a heat generating member interposed between the first and second sides, and the heat generating element being fixed to an inner side of the second stretch sheet of the stretch bag via a fixing part, such that stretchability of the stretch bag is not impaired, wherein the first stretch sheet has a load, at 50% extension, of 5N/2.5 cm or less in its most stretchable direction, the inner side of the second stretch sheet and the second side of the heat generating element facing the inner side of the second stretch sheet are flat except at their respective perimeters, the stretch bag has a predefined bendable central joint that divides the stretch bag evenly at a width-wise centerline of the stretch bag that runs in a width direction corresponding to the width of the stretch bag, in a plan view of the heat generating eye mask, a length of the fixing part, which is greater than a width of the fixing part, extends in the width direction of the stretch bag so as to overlap both a first edge and a second edge opposite the first edge of the heat generating element, the fixing part is centered about a length-wise centerline of the stretch bag that runs in a length direction corresponding to the length of the stretch bag, the length-wise centerline is perpendicular to the width-wise centerline of the stretch bag, and in the plan view of the heat generating eye mask the fixing part is arranged closer to a third edge of the heat generating element than a fourth edge of the heat generating element opposite the third edge, the third edge being closer to the predefined bendable central joint than the fourth edge.
