PROBLEM TO BE SOLVED: To simultaneously reduce faults when using resin as both materials and faults when using metal as one material, regarding a shaft member 3 and a bearing member (a housing 13) which bears bearing function in a rotation angle detector 1. SOLUTION: The rotation angle detector 1 constitutes the bearing function by supporting the resin shaft member 3, excelling in bearing performance with a friction coefficient based on a Suzuki-type wear test being 0.20 or less, directly to the resin housing 13. Since both the shaft member 3 and the housing 13 that serve as the bearing member are provided using resin as material, nonconformities for the case of using metal as material can be eliminated. The shaft member 3 is provided in substantially a cylindrical shape, and by having a yoke 5 that uses metal as material stuck to a surface portion of an inner peripheral surface 4, including a center portion 17, the nonconformities for the case of using resin as the material can be reduced.
