ばすことができる。According to the present invention, the heat generating element is provided at the same position as or on the heat generating side of the heat generating side tip of the power supplying member which is independent of the power supplying member and whose one end is in contact with the connecting portion of the heat generating element. By providing a conductive member whose other end is arranged at the connecting portion at the position where the electric power is supplied, the current supplied from the external power source is
The current flowing to the heat generating part through the heat generating side end of the power supply member,
It is branched into a current flowing to the heat generating portion through the heat generating side end of the conductive member. Therefore, the amount of heat generated at the tip of the power supply member is reduced, the generation of heat spots can be prevented, and the life of the heating element can be extended.
