摘要： PROBLEM TO BE SOLVED: To provide a permanent magnet unit capable of being constituted at a low cost, and suppressing the decline of magnetic characteristics even while a magnetization direction is practically inclined, and to provide a magnetic field generator provided with it.
SOLUTION: The permanent magnet unit 10 is provided with a pair of permanent magnets 12 respectively formed in a cube shape. The magnetization directions A of the pair of permanent magnets 12 are respectively vertical to a surface 14a and a surface 14b, and parallel with a surface 16 other than the surfaces 14a and 14b. The pair of permanent magnets 12 are connected such that the surface 14a of one permanent magnet 12 and the surface 16 of the other permanent magnet 12 are in contact and are magnetically coupled while making the magnetization directions A of each other be different by 90°. Thus, the magnetization directions A of the pair of permanent magnets 12 are combined and the magnetization direction of the permanent magnet unit 10 becomes a practically inclined magnetization direction B. The permanent magnet unit 10 constituted in such a manner is used in the magnetic field generator or the like for an MRI apparatus for instance.
