PROBLEM TO BE SOLVED: To provide a silicon carbide heating element capable of preventing active oxidation in an inner diameter part of a hollow heating element.SOLUTION: A silicon carbide heating element is used as a heat source of a furnace, and mounted such that an end part thereof is inserted through a furnace wall through hole provided in a furnace wall of the furnace and a heating part thereof is disposed in the furnace. The heating element has a hollow form, and a through hole penetrating in a hollow inner part (inner diameter part) from a side face of the heating element is provided in the heating part or the end part of the heating element. 【目的】中空状の発熱体の内径部におけるアクティブ酸化を防止することができる炭化珪素発熱体を提供する。【構成】加熱炉の熱源として用いられる炭化珪素発熱体で、該発熱体の端部を加熱炉の炉壁に設けた炉壁貫通穴に挿通させ炉内に発熱部が配設されるよう取り付けられる炭化珪素発熱体において、発熱体は中空状のものであり、発熱体の発熱部または端部に、発熱体の側面から中空状の内部（内径部）に貫通する貫通穴を設けたことを特徴とする。【選択図】図１
