Abstract
A trimmed resistor is provided which has no directional feature when used and is easily mounted on a printed base board. In the trimmed resistor, there are formed four external electrodes arranged at peripheral portions of a rectangular insulation base plate in a point symmetrical distribution about a center of the insulation base plate, a film-like resistance body connected with all of the external electrodes, and a protective film covering the film-like resistance body. Two electrodes among the above-mentioned four electrodes are used as resistor terminals, and a cut slit for trimming is formed in the resistance body longitudinally or as starting from a side of the electrodes serving as resistor terminals.
