To provide a heating element having high conductivity and high mechanical strength concerning the heating element and a heating member.SOLUTION: A heating element includes: a zinc oxide phase containing Al; and zinc oxide-based ceramic containing a cordierite phase or a willemite phase. The zinc oxide-based ceramic contains the cordierite phase in a proportion of 10% by mass or more and 26% by mass or less. In the zinc oxide-based ceramic, the surface of the zinc oxide-based ceramic containing the willemite phase in a proportion of 20% by mass or more and 40% by mass or less has a higher proportion in the cordierite phase in comparison with the inside. The surface of the zinc oxide-based ceramic has the higher proportion in the willemite phase in comparison with the inside.SELECTED DRAWING: None
【課題】発熱体および発熱部材に関し、高い導電性と高い機械的強度を有する発熱体を提供する。【解決手段】発熱体は、Ａｌを含有する酸化亜鉛相と、コージエライト相またはウイレマイト相とを含む酸化亜鉛系セラミックスを備えている。酸化亜鉛系セラミックスはコージエライト相を１０質量％以上２６質量％以下の割合で含む。酸化亜鉛系セラミックスはウイレマイト相を２０質量％以上４０質量％以下の割合で含む酸化亜鉛系セラミックスの表面は、内部に比べて、コージエライト相の割合が高い。酸化亜鉛系セラミックスの表面は、内部に比べて、ウイレマイト相の割合が高い。【選択図】なし
