Abstract

See full text

Discussed are 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 oxygen content of 1 to 4 wt %, so that it can be used even at a high operating temperature of 400° C. or more, suppresses the elution of the material itself, has high fracture toughness, a low coefficient of thermal expansion, and heat resistance, and furthermore, ensures conductivity by having improved adhesive strength with respect to at least one of a substrate and an insulating layer, and controlled electrical resistivity.
