PROBLEM TO BE SOLVED: To provide a magnetic circuit block for magnet device that can be manufactured easily and efficiently. SOLUTION: A connecting member 20, having a T-shaped cross section, is formed by drawing a nonmagnetic material. Into the space surrounded by a top board section 21, side board sections 22, interposed section 23, and locking claw sections 24 of the connecting member 20, a pair of precast magnetic members 7 is inserted. The connecting member 20 holes the magnetic members 7 by means of the interposed section 23 and locking claw sections 24, by covering and wrapping the external surfaces of the magnetic members 7 from the upper surfaces of the members 7 to the side faces 7b of the members 7, by means of its top board section 21 and side board sections 2 on a side opposite to the side on which housing recessed groove sections are provided and maintaining a prescribed clearance between the members 7, by interposing the interposed section 23 in between the members 7. The magnetic circuit block is formed, by press-fitting and fixing a round bar 28 between the facing fixing recessed groove sections 9 of the magnetic members 7.
