Abstract

A thin-thickness variable resistor is provided, which is capable of stabilizing electrical connection between metallic terminals and a resistor by increasing the holding strength for a second terminal by a substrate while preventing the bending strain during the bending work from spreading to a conductive portion conductive to the resistor. A variable resistor comprises a substrate, metallic terminals formed in the substrate by insert-molding, and a slider sliding on a resistor formed on the substrate, wherein the slider is rotatably attached by crimping an eyelet formed in a first metallic terminal. External-connecting portions of the metallic terminals are extended from the bottom portion of the substrate to be bent upwardly along sides of the substrate. Anchor portions to be embedded into the substrate are unitarily formed in the vicinity of the conductive portions of the second metallic terminals conductive to the resistor and between the conductive portions of the second metallic terminals and the external connection portions thereof.
