<p>PROBLEM TO BE SOLVED: To provide a position detection device having a highly-accurate, small- sized and simple structure, excellent in compensation performance of a temperature characteristic. SOLUTION: This device includes first and second detection coils A, B excited by an alternating-current signal, and a magnetic response member 12 arranged so as to bring about different impedance changes to each detection coil corresponding to the position which is a detection object. A position detection signal corresponding to the position which is the detection object is generated by operating the ratio of a detection signal level corresponding to the impedance of each detection coil.</p> |
