Abstract
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 10−4 to 10−2 Ωcm, 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.
