To suppress increase in size of a whole motor due to a magnetic flux guiding member in a mechanical and electrical integrated type motor having the magnetic flux guiding member for guiding a magnetic flux from a sensor magnet to a magnetic sensor.SOLUTION: A mechanical and electrical integrated type motor includes: a housing 4 for housing a motor; a sensor magnet 30 provided in the housing; a circuit board 10 provided on a side opposite to the sensor magnet of the housing; a plurality of magnetic sensors 24 mounted on the circuit board to detect a magnetic flux from the sensor magnet; and a plurality of magnetic flux guiding members 8 formed of a high-permeability material to guide the magnetic flux from the sensor magnet to each of the plurality of magnetic sensors. Each of the plurality of magnetic flux guiding members is fixed in a state of protruding toward the sensor magnet side at a position opposed to the sensor magnet of the housing, and a groove 32 into which a tip section of the magnetic flux guiding member is inserted is provided with the sensor magnet.SELECTED DRAWING: Figure 5 【課題】センサマグネットからの磁束を磁気センサに導く磁束誘導部材を備えた機電一体型モータにおいて、磁束誘導部材によってモータ全体が大きくなるのを抑制する。【解決手段】機電一体型モータは、モータを収容した筐体４と、筐体内に設けられたセンサマグネット３０と、筐体のセンサマグネットとは反対側に設けられた回路基板１０と、回路基板に実装され、センサマグネットからの磁束を検出する複数の磁気センサ２４と、高透磁率材料にて構成され、センサマグネットからの磁束を前記複数の磁気センサにそれぞれ導く複数の磁束誘導部材８とを備える。複数の磁束誘導部材は、筐体のセンサマグネットとの対向位置に、それぞれ、センサマグネット側に突出した状態で固定されており、センサマグネットには、磁束誘導部材の先端部分が挿入される溝部３２が設けられている。【選択図】図５
