PROBLEM TO BE SOLVED: To provide an angle position detecting device which is compatible with high resolution and with absolute measurements with a simple constitution of the device. SOLUTION: The angle position detecting device is constituted so as to output signals corresponding to the position of the rotation angle of the rotational axis, comprises multiple resolvers 20, 30, having different number of poles to each other, and is provided with the function of correcting accuracy of the resolver having the smaller number of poles 20 referring to the resolver with the larger number of poles 30. Especially, the device is preferably provided with means S4-S6 for reading the output of the resolver 20 abs of the smaller number of poles 20 at multiple positions of rotation of the rotation axis based on the output of the resolver of the larger number of poles 30; and means (S7-S8) for calculating the correction value, based on the output of the resolver 30 of the larger number of poles, and the output of the resolver 20 of the smaller number of poles.
