PROBLEM TO BE SOLVED: To eliminate shortcomings such that conventionally, a foot-warming product and a frame to protect feet are separate products, and therefore, have been inconvenient; and provide a far infrared framed hot water bottle by combining the foot-warming product and the frame to make them convenient; and also, utilize a far infrared ray radiation required for patients. SOLUTION: A frame prevents a kakebuton from slipping, and fixes a hot water bottle. Also, the frame eliminates the burden of a weight applied to feet. For the hot water bottle, the replacement of water is required only once per year. The boiling of hot water can be performed in 7 to 8 minutes as well, and a thermostat (turned off at 60 deg.C) is attached so that the hot water may not become higher than 60 deg.C. Thus, the turning on and off can be automatically performed. Far infrared rays have become natural far infrared rays by coating iron with the powder of a rock of which the radiation efficiency is favorable. Regardless of occasions, when the body becomes cold or chilly, the hot water bottle becomes warm by simply turning on the switch. For this far infrared framed hot water bottle, the frame, the hot water bottle and the far infrared rays are combined.
