Abstract: A noise-preventing resistor has a structure in which a resistance wire is wound around an outer circumferential surface of a core, cap terminals are attached to either end part of the core, and part of an insulative coating (resin coating) covering the resistance wire and part of the resistance wire positioned underneath the insulative coating are cut, forming peeled regions exposing the resistance wire. As a result, conduction between the cap terminals and the resistance wire in the noise-preventing resistor is ensured.

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).
