A variable resistor for increased assembly efficiency and decreased influence by environmental changes is disclosed. The variable resistor includes a closed end main casing, an external terminal held in the main casing and connected to the insulating substrate, a side receiver movably held in the casing, a shaft for moving the slider receiver, and a cover for closing an opening of the casing. The shaft is supported by a bearing formed on the cover to protrude from the cover and is further provided with a fall-preventive means. The terminal and substrate are both connected on the opening side of the casing.
