PROBLEM TO BE SOLVED: To provide sensor structure capable of reducing a cost while enhancing reliability, and a manufacturing method for a sensor. SOLUTION: A permanent magnet 22 is stored inside a storage part 31 from a storage port 32 of a holder 21, and an overhung part 34 is arranged in a permanent magnet 22 end face side to be extended from a storage port 32 wall face. A printed board 23 is positioned in a plane part 26 of the holder 21, and a Hall IC 62 is arranged in an end face side of the permanent magnet 22 to form a storage component 13. An end face 72 of a case 11 is arranged to contact closely with an iron sheet 73, and the storage component 13 is stored in the case 11. The permanent magnet 22 is attracted thereby to an iron sheet 73 side by magnetic force to contact closely with the Hall IC 62 and the end face 72 of the case 11. A sealant 82 is injected into the case 11 under this condition, and is solidified to form the rotary sensor 1. COPYRIGHT: (C)2006,JPO&NCIPI
