Abstract
A heating element in which, in a connecting portion of a rod portion in which the rod portion is connected to a heat generator, a connecting unit is provided in a face of the rod portion on which the rod portion is connected to the heat generator, a feeder terminal for feeding power to the heating element is formed on a face of the rod portion opposite to the face in which the connecting unit is provided and the rod portion includes, at the feeder terminal, a securing unit for securing the heating element, and the rod portion includes a hollow portion between the connecting unit and the securing unit. This provides a heating element that can prevent corrosion of a feeder terminal, possesses high durability, can be produced at low cost, and has a good temperature distribution.
