A housing can be of simple structure because the first wall portion, the second wall portion, and a side portion are integrally formed. The housing is brought into contact with the resin-formed part of a coil at an end opposite to the side portion of the second wall portion. This prevents the relative turn in the peripheral direction between the coil and the housing and the movement to the side portion of the coil. On this account, the positional relationship between the coil and the housing can be prevented from becoming incorrect and the winding or the wiring part of the coil through which current flows can be prevented from being brought into contact with the housing of a conducting body. The positional relationship between the coil and the housing can be determined with precision without causing the complex structure of the coil and the housing.
