Abstract: To provide a wire-wound resistor provided with high reliability and that retains the basic functionality of the wire-wound resistor, and a method for manufacturing the same. A wire-wound resistor in which a resistor wire is wound onto an external periphery of a core (11) obtained by bundling fibrous insulators, and a connection terminal (13) is attached to both ends of the core (11) and connected to the resistor wire (12a), wherein the core (11) is impregnated with a binder in the portion (11a) in the vicinity of the external periphery. The binder (1) is preferably not included in a center portion (11b) of the core (11).
