たものである。 A metal pipe 1 is made of a heat-resistant alloy such as stainless steel or Incoloy, and is filled with a filler 2 made of an electrical insulator such as magnesia powder. Reference numeral 3 denotes a heating wire, which has a coil shape made of iron chrome or the like, is buried in the filling material 2, and terminals 4 are connected to both ends of the heating wire. 5 is a covering member, which is made of hollow cylindrical inorganic fibers such as ceramic fibers or glass fibers, and has a thickness of 500 to 1000.
It has a heat resistant temperature of .degree. C. and is coated on the outer surface of a metal pipe 1 and fixed with an inorganic adhesive. Reference numeral 6 denotes a radiation layer, which is made of a ceramic layer such as MnO 2 or Fe 2 O 3 and has a high emissivity, and is provided on the outer surface of the covering member 5.

ある。 As described above, according to the present invention, the outer surface of the metal pipe of the sheathed heater is covered with a covering member made of inorganic fibers, and an infrared radiation emitting layer made of ceramics is provided on top of the covering member, so that the particle size of the ceramics is reduced by the covering member. Since the mixture is mixed with an inorganic adhesive used to cover the outer surface of a metal pipe, applied to the covering member, and baked, the particle size can be selected from a wide range, and it emits far-infrared rays that match the absorption wavelength of the object being irradiated. do. Furthermore, compared to the conventional case where it is directly applied and baked on the outer surface of a metal pipe, there is less difference in thermal expansion and it is difficult to peel off, and it does not require plasma spraying equipment, so it is possible to provide an inexpensive far-infrared heater.
