摘要：
A sheathed heater comprising a metallic sheath, such as a stainless steel sheath, an electric heating element disposed within the sheath so that an electric current can be supplied thereto, and a filling material filled in the sheath for insulating the heating element from the sheath and the coils of the heating element from each other. Aluminum nitride powder is used as the filling material to prevent oxidation of the heating element by the oxygen discharged from the filling material.
