Provided is a resolver capable of increasing an accuracy of a detected angle of the resolver. The resolver includes: a stator; and a rotor, wherein the rotor includes a plurality of salient poles; wherein the stator includes: a stator core having a plurality of teeth, and a plurality of winding groups each of which is provided on each of the plurality of teeth, wherein the winding groups are divided into two systems, wherein the numbers of turns of the excitation windings are distributed in a form of a sine wave of Ne-th spatial order, wherein each of the numbers of turns of a first output windings and the numbers of turns of a second output windings are distributed in a form of a sine wave of |Ne±Nx|-th spatial order, and wherein the following expressions are satisfied,Nout1=N1 cos{|Ne±Nx|(i−1)/Ns×2Π+α},Nout2=N1 cos{|Ne±Nx|(i−1)/Ns×2Π+β}, and90(deg)<|α−β|<140(deg).
