1. A magnetic field generating unit that is fixed to an object that moves relative to magnetic field detecting means comprising:
a magnetic field generator;
a first support structure that is fixed to the object; and
a second support structure that is independent of the first support structure, wherein the second support structure is supported by the first support structure and supports the magnetic field generator,
wherein the first support structure is elongate in a first direction, the second support structure is elongate in a second direction that is orthogonal to the first direction, and the second support structure is formed of a resin that is bonded both to the first support structure and to the magnetic field generator.
