Abstract
The present invention is a load resistor that receives power transmitted from an apparatus and performs an energization test on the apparatus. The load resistor is characterized by comprising a rod-shaped resistive base body that is energized with the power and generates heat, a pipe-shaped protective member through which the rod-shaped resistive base body penetrates, and rod-shaped resistors having an insulation member that are packed in between the rod-shaped resistive base body and the protective member, the rod-shaped resistive base body having used therein a stretched nichrome wire that is wound in the shape of a coil.
