Abstract
A resistor 1 is used in high-fidelity amplifiers for audio equipment. The resistor 1 includes a cylindrical resistor body 2, a tubular sheath 3 into which the resistor body 2 is coaxially inserted, and a conductive film portion 31a formed on the inside surface 3a of the sheath 3. The conductive film portion 31a faces to a resistance film 22 covering the surface of the resistor body 2 with an annular space 6. An insulating slit 32 is formed at a central point along the resistor axis 1a, separating the conductive film 31 into left and right parts that are electrically isolated from each other. The sheath covering the resistor body 2 prevents distortion of signals in the resistance film 22 caused by extraneous electrostatic induction charges.
