The present invention relates to a rotation angle detection device mainly used for rotation angle detection of a steering wheel of an automobile and the like. In the rotation angle detection device of the present invention, support portions for supporting lower surfaces of magnets and retention portions for retaining upper surfaces of the magnets are provided in respective accommodation portions of first and second detection bodies. The magnets are turned in the accommodation portions, and the magnets are press-fitted into lower surfaces of the retention portions so as to be retained and fixed between the support portions and the retention portions. Thereby, an inexpensive rotation angle detection device in which the magnets can be easily and reliably installed in the detection bodies with a simple configuration without individually using holders can be realized.
