A rotating electric machine suitable for use as a starter-generator of an engine (E) of a saddle-ride type vehicle, particularly a motorcycle, is provided that achieves a size reduction with a simple structure. A magnetic sensor element (H) is incorporated in a case main body (31) of a magnetic sensor unit (30) for detecting the rotational position of a rotor (20). An extension portion (25) is provided to a permanent magnet (MG). The extension portion (25) extends toward an engine (E) beyond an end surface at an engine side of teeth (13) of a stator (10). The magnetic sensor element (H) is arranged closer to the engine (E) than an end surface at the engine side of the extension portion (25) of the permanent magnet (MG) is to the engine (E). The magnetic sensor element (H) is arranged such that it is at least partially located within a range of ±g in the radial direction from an inner circumferential end surface of the permanent magnet (MG), where g represents a gap length between an outer circumferential end surface of the teeth (13) and the inner circumferential end surface of the permanent magnet (MG). |
