Abstract
A heating resistancecomprises a shaped body of a band made of a conductive material obtained by bending the band in a shape of a wave. The heating resistanceis fixed to a substrate made of an insulating material to obtain a heater. Alternatively, the heating resistance comprises a wound body of a band made of a conductive material. According to the present invention, the heating value per a unit length can be easily designed and changed, and the reliability can be improved and abnormal heat generation can be prevented at the interface where the heating value per a unit length is changed.
