PROBLEM TO BE SOLVED: To provide a magnet structure excellent in durability against an environment where temperature changes, and a rotation angle detector using the same.SOLUTION: A magnet structure 10 includes: a columnar member; and a bonded magnet molded body which has an annular part surrounding an outer peripheral face of the columnar member in a hoop direction. The bonded magnet molded body has a thermal expansion coefficient larger than the columnar member by 2.0×10/K or more.SELECTED DRAWING: Figure 1 |
