To provide a rotation angle detector which can be downsized.SOLUTION: A rotation angle detector 2 includes: a first rotary member 3 and a second rotary member 4 which rotate at different rates in association with rotation of a steering shaft 171; a first magnet 51 attached to the first rotary member 3; a second magnet 52 attached to the second rotary member 4; and a magnetic field detection element 6 for detecting a magnetic field of the first magnet 51 and a magnetic field of the second magnet 52. The magnetic field detection element 6 is disposed at a position where the rotation axial line O1 of the first rotary member 3 and the rotation axial line O2 of the second rotary member 4 intersect each other.SELECTED DRAWING: Figure 6 【課題】小型化が可能な回転角検出装置を提供する。【解決手段】回転角検出装置２は、ステアリングシャフト１７１の回転に伴って異なる速度で回転する第１及び第２の回転部材３，４と、第１の回転部材３に取り付けられた第１の磁石５１と、第２の回転部材４に取り付けられた第２の磁石４と、第１の磁石５１の磁界及び第２の磁石５２の磁界を検出する磁界検出素子６とを備える。磁界検出素子６は、第１の回転部材３の回転軸線Ｏ１と第２の回転部材４の回転軸線Ｏ２とが交差する位置に配置されている。【選択図】図６
