Document Type and Number:
Japanese Patent JP4010662
Kind Code:
B2
Abstract:
A heater comprises a cap 20 formed by joining and fixing together curved peripheries 10a as peripheries of two semi-elliptical heat-generator-containing sheets 10 of generally the same shape. The heat-generator-containing sheet 10 comprises a waterproof inner layer sheet 2, an air-permeable sheet 5 disposed so as to cover the entire surface of the inner layer sheet 2, and a plurality of heat generators 3 interposed between and held by the inner layer sheet 2 and the air-permeable sheet 5, which generate heat when in contact with an air. The heat generators 3 are disposed substantially over the entire surface of the cap 20. The heat-generator-containing sheets 10 are joined and fixed together with the respective inner layer sheets 2 being the inner surface. The heater realizes a simple handling when in use, a small temperature variation, and simple fabrication process.
