<p>PROBLEM TO BE SOLVED: To provide a resistor which is superior in micro linearity and high in sliding durability and a variable resistor which is equipped with the resistor, high in accuracy, and has a long service life. SOLUTION: A lower layer 2 and an upper lower 3 are laminated, a slider 5 slides on the surface of the upper layer 3, and the upper layer 3 is lower in resistivity than that of the lower layer 2.</p> |
