<P>PROBLEM TO BE SOLVED: To provide a magnetic rotation detector where a magnet body and a magneto-sensitive element can be aligned with each other with high precision without the need for a time-consuming processing, and also provide a method of manufacturing the detector. <P>SOLUTION: In this magnetic rotation detector 10, a ring 15 is fixed to a plate-like section 315 of a first case body 31 interposed as a partition member between a magnet body 20 and the magneto-sensitive element 42, and the positions of the magnet body 20 and the magneto-sensitive element 42 are determined with reference to the ring 15. In other words, in the method of manufacturing the magnetic rotation detector 10, the position of the magneto-sensitive element 42 on the first case body 31 is determined with reference to the ring 15, and the positions of the magneto-sensitive element 42 and the magnet body 20 are determined with reference to the ring 15 using a spacer 50 and a tool. Therefore, the position accuracy between the magneto-sensitive element 42 and the magnet body 20 is high. <P>COPYRIGHT: (C)2010,JPO&INPIT |
