Discussed is a surface type heating element which generates heat using electricity and a method of manufacturing the surface type heating element. The surface type heating element includes a NiCr alloy and has an adhesive strength of 3 N or more with respect to a substrate or an insulating layer and an electrical resistivity of 10to 10Ωcm, and thus it can be used even at a high operating temperature of 400° C. or more, suppresses the elution of the material itself, and has high fracture toughness, a low coefficient of thermal expansion, and heat resistance, resulting in improvement of the reliability and lifetime of the product.

Surface type heating element and manufacturing method thereof

A surface heater including a substrate, an insulating layer positioned on the substrate, and a heater layer positioned on the insulating layer, wherein the insulating layer and the heating layer are co-fired.
