A variable reluctance type angle detector 1 is provided with a rotor 5 and a stator 4 . The rotor 5 is provided rotatably on the stator 4 . The stator 4 has twelve teeth 2 disposed circumferentially. An excitation wire 7 , a SIN output wire 8 , and a COS output wire 9 are wound around the teeth 2 . In the case where numbers of 1 to 12 are assigned clockwise to the twelve teeth 2 , the excitation wire 7 is wound around each of the first, second, third, seventh, eighth, and ninth teeth 2 in a concentrated fashion to generate an identical polarity and wound around each of the fourth, fifth, sixth, tenth, eleventh, and twelfth teeth 2 in the concentrated fashion to generate a polarity that is reverse to the polarity of the first, second, third, seventh, eighth, and ninth teeth 2 . The SIN output wire 8 is wound around each of the second, fourth, and twelfth teeth 2 in the concentrated fashion to generate an identical polarity and wound around each of the sixth, eighth, and tenth teeth 2 in the concentrated fashion to generate a polarity that is reverse to the polarity of the second, fourth, and twelfth teeth 2 . The COS output wire 9 is wound around each of the third, fifth, and seventh teeth 2 in the concentrated fashion to generate an identical polarity and wound around each of the ninth, eleventh, and first teeth 2 in the concentrated fashion to generate a polarity that is reverse to the polarity of the third, fifth, and seventh teeth 2.
