A rotor () of a rotation angle sensor is configured by forming a band-shaped main body () of a magnetic steel sheet into a cylindrical shape so that a thickness direction of the band-shaped main body () is set as a radial direction. First undulations () are provided at a substantially constant pitch on one arc-shaped edge portion of the band-shaped main body (), and second undulations () are provided at a substantially constant pitch on the other arc-shaped edge portion. A first stator () is disposed to face the first undulations () of the band-shaped main body () of the rotor (), and a second stator () is disposed to face the second undulations ().
