Abstract: PURPOSE:To enhance the determining accuracy of a position and to improve signal accuracy by providing the engaging part of a Hall element that is provided in a molded frame, and providing a connector part that is formed in the molded frame as a unitary body. CONSTITUTION:When the cut part of a magnetic-flux shutter 8 is located at a gap part G by the rotation of an internal combustion engine and the like, the magnetic flux which is generated with a magnetic-flux generating member 5 forms a magnetic path shown by a broken line A. The magnetic flux acting on a Hall element 2 becomes a 'large' state. When the magnetic body part of the magnetic-flux shutter 8 is located at the gap part G, the magnetic flux which is generated with the magnetic-flux generating member 5 forms a magnetic path shown by a broken line B. The magnetic flux acting on the Hall element 2 becomes a 'small' state. Thus, the change in magnetic flux in synchronization with the rotation of the internal combustion engine is imparted to the Hall element 2. An electric signal corresponding to the change in magnetic flux due to the Hall effect is generated. The electric signal is guided to an external circuit through a connector part, and the waveform is processed. Thus a crank angle can be detected.
