Abstract: Disclosed is a fuse resistor provided on an electrical circuit to protect the electrical circuit and elements. The fuse resistor includes a substrate on which first and second resistive terminals and fuse terminals are formed, first and second resistive elements surface-mounted on the first and second resistive terminals and dividing applied current or voltage, and a temperature fuse surface-mounted on the fuse terminals and broken by heat generated from the first and second resistive elements. If overcurrent or overvoltage is applied, the first and second resistive elements generate heat and the temperature fuse is broken by the generated heat.
