Claims

[Claims for Utility Model Registration] A horseshoe-shaped resistance layer is formed around a through hole formed in the center of a ceramic substrate, and electrode terminals are connected from both ends of the resistance layer to one end of the ceramic substrate at a distance from each other. and a semi-fixed resistor in which a shaft of a slider that slides on the resistance layer is rotatably attached to the through hole, wherein the electrode terminal forming portion of the slamic substrate is thinner than the remaining portion. A semi-fixed resistor characterized in that it is formed in the part.
