The position detection device comprises a coil section (4); a target section (3) which includes a magnetism-responsive member constructed to cause the inductance of a coil included in said coil section (4) to vary in accordance with a position relative to the position of a detection object; a self-oscillation circuit (10) comprising the coil of the coil section (4) and a capacitor (14, 15); and an output circuit (21, 22, 23) adapted to output position data of the detection object based on an oscillation output signal of the self-oscillation circuit (10).The coil section (4) includes a plurality of coils (4a, 4b'; 41, 43', 42, 44'; 41, 42) at a predetermined interval from each other. The self-oscillation circuit (10) constructs an inductance element for self-oscillation by connecting a plurality of the voltage-dividing circuits in parallel with each other, the coil (4a, 4b'; 41, 43', 42, 44'; 41, 42) being incorporated therein. A plurality of the oscillation output signals (+DVout, - DVout; +sinOUT, -sinOUT, +cosOUT, -cosOUT) are output from the voltage-dividing points of individual ones of the voltage-dividing circuits.
