抵抗器。 A rotor member is rotatably formed by forming a substantially bowl-shaped metal plate on the upper surface of an insulating substrate on which an arcuate resistance film is formed, and forming a flange portion around the bowl-shaped portion. an arc-shaped slit groove is provided in the flange portion of the rotor member, and a portion of the flange portion outside the slit groove is formed as a sliding terminal portion that contacts the resistive film;
In a chip type variable resistor in which the sliding terminal portion is divided into an inner sliding terminal piece at the inner peripheral portion and an outer sliding terminal piece at the outer peripheral portion, the outer peripheral edge of the flange portion of the rotor member A ring body formed by folding back toward the lower surface of the flange portion is integrally connected to a portion opposite to the sliding terminal piece, and the ring body is adjacent to the sliding terminal piece at the flange portion. A chip-type variable resistor characterized in that at least one auxiliary sliding terminal piece that contacts the resistive film is formed in a portion where the resistive film is connected.
