PROBLEM TO BE SOLVED: To provide a highly reliable variable resistor for hardly generating a short-circuit failure between terminals even if insert-molding an insulating substrate in a housing made of synthetic resin. SOLUTION: This variable resistor is provided with a plate-shaped insulating substrate 7 formed with a resistor 8 and a collector 9, a plurality of mounting holes 7b formed at one edge side of the insulating substrate 7, a plurality of terminals 10 fixed to the plurality of mounting holes 7b so as to be conducted to the resistor 8 and the collector 9, and extended from one edge side of the insulating substrate 7 to the outside, a holding member 11 made of synthetic resin in which the fixed sections of the plurality of terminals 10 and the insulating substrate 7 are embedded in such a status that the resistor 8 and the collector 9 are exposed and a slider 6 sliding on the resistor 8 and the collector 9 and an insulating protrusions 11b and 11c extended to a direction crossing the plane face of the insulating substrate 7 between fixed sections of the plurality of terminals 10 fixed to the insulating substrate 7.
