するという重大な欠点がある。 Recently, heaters that emit far-infrared rays have been attracting attention. Conventional far-infrared heaters include those in which an oxide that generates far-infrared rays is coated or sprayed on the surface of a metal pipe of a sheathed heater. However, this configuration has a serious drawback in that the oxide peels off from the metal pipe due to thermal cycles associated with repeated use of the heater.

外皮を構成する焼結層を形成することができる。 The method for manufacturing a far-infrared heater of the present invention includes surrounding a metal resistance heating element with a mixture of magnesia, calcium oxide, silicon oxide, and boron oxide.
The filling density of the mixture is increased by filling a metal pipe such as aluminum that can be removed by heat treatment and rolling the metal pipe, and then melting and removing the metal pipe by heat treatment. The mixture is sintered, and according to this method, a sintered layer constituting a strong outer skin of the heater can be formed.

に、混合粉末を焼結した。Example 1 4% by weight of boron oxide (hereinafter simply expressed as %), 5% of silicon oxide, and 5.5% of calcium oxide were added to magnesia powder, and this mixed powder was filled into an 8 mm diameter aluminum pipe together with a nichrome wire. Next, the pipe was rolled to a diameter of 7 mm, and then heat treated in a reducing atmosphere at 1200°C to melt and remove the aluminum pipe and sinter the mixed powder.
