SENSOR

PROBLEM TO BE SOLVED: To put a Hall element exactly in the non-magnetic flux domain of a U-shaped magnet, of a sensor containing the Hall element interior of the housing. SOLUTION: The sensor has a pair of facing sections 51 facing interspatially each other and is equipped with the U-shaped magnet 50 forming the non-magnetic flux domain A between the pair of the facing sections 51, a Hall element 80, output voltage of which varies depending on passage of the magnetic flux density, a spacer 40 specifying positional relationship of the Hall element 80 and the U-shaped magnet 50 so as to locate the Hall element 80 in the non-magnetic flux domain A of the U-shaped magnet 50, and a housing 10 covering the spacer 40.
