ABSTRACT:
An improved variable resistor for use in electrical and electronic equipment which includes a substrate having fixed side terminals integrally molded in it so that forward end portions of the fixed side terminals are exposed to the surface of the substrate, a resistant layer formed on the surface of the substrate so as to cover the exposed forward end portions of the fixed side terminals at opposite end portions of the resistant layer, a variable side terminal provided on the substrate, and a slider movably disposed on the substrate for sliding movement over the resistant layer so as to adjust resistance of the variable resistor and in which the fixed side terminals are applied with solder coating at their predetermined portions except for the exposed forward end portions.
