A position sensor comprises: a cosine coil and a sine coil as excitation coils which generate excitation signals; a detection coil which detects the excitation signal generated from the cosine coil and the sine coil; and a phase-difference detector serving as a converter that calculates a position of the detection coil based on the excitation signal detected by the detection coil. The cosine coil and the sine coil are plate-shaped conductors each including: a plurality of vertically bent segments which function as a coil; and connecting wire portions provided on both sides of the segments to connect the segments.
