<p>PROBLEM TO BE SOLVED: To provide a trimmer capacitor which has a plurality of kinds of variable capacitance ranges and is suitable for fine adjustment according to application modes. SOLUTION: This trimmer capacitor consists of the following; a first fixed electrode 21 and a second fixed electrode 22 which are different in surface electrode area, and a variable electrode 4 capable of rotating which faces the fixed electrodes 21, 22 via specified dielectrics. A specified electrostatic capacity of the trimmer capacitor is introduced by pivoting the variable electrode 4 and controlling the facing area of the first fixed electrode 21 and the variable electrode 4, and/or the facing area of the second fixed electrode 22 and the variable electrode 4.</p> |
