The present invention relates to a wire-wound fuse resistor, which has: an insulating rod which has a first end and a second end; one metal wire having a wire head and a wire tail, being helically wound around the insulating rod from the first end to the second end, and being cut at a middle portion thereof to form a first winding wire and a second winding wire, which are separated from each other; a connection part disposed at the cut portion for electrical connection between the first winding wire and the second winding wire, in which the melting temperature of the connection part is lower than that of the one wound metal wire, wherein the connection part is cut off depending on a predetermined melting temperature or melting speed of the wire-wound fuse resistor.

Provided is a surface mount resistor that can be stably mounted without the need for lead wires to be to flattened. The surface mount resistor includes a first resistive element and a second resistive element arranged in parallel, the first resistive element having first lead wires at opposite ends thereof, and the second resistive element having second lead wires at opposite ends thereof. The first resistive element and the second resistive element are integrated by being covered with a sheath. The first lead wires and the second lead wires are arranged such that they protrude outward in a direction of an axis beyond the sheath. The first lead wires and the second lead wires are bent alongside surfaces and a bottom surface of the sheath.
