A highly accurate rotation angle detection device is realized by correcting a detecting position error caused by a machining error such as deterioration of roundness of an internal diameter of a stator. The rotation angle detection device is provided with a stator ( 12 ), which is provided with an exciting winding of one phase and two-phase output windings, and a rotor ( 13 ) having salient poles, in which the stator ( 12 ) has a plurality of teeth ( 11 ), the two-phase output windings are wound around the plurality of teeth, and the plurality of teeth include teeth for which the number of turns of the output windings is N and at least one of teeth for which the number of turns of the output windings is N±m (it is assumed that N and m are positive integers and N>m) and teeth for which the number of turns is m.
