Bond magnet and manufacturing method of the same

A bond magnet comprising:

• a first filament;
• and
• a second filament, wherein
• the filaments are bonded to each other to form a bond magnet,
• each of the filaments is a filamentous member containing a resin material and magnetic powder dispersed in the resin material, and has magnetic anisotropy, and
• a surface layer portion of one of the plurality of filaments has a ratio of the resin material to the magnetic powder greater as compared with a central portion on a central side of the surface layer portion of the one filament.

A bond magnet comprising:

• a first set of basic components;
• and
• a second set of basic components, wherein
• the sets of basic components include a first component and a second component as one set thereof,
• the sets of basic components form one ring-shaped body by arranging each of the plurality of sets of basic components in a circumferential direction with respect to a center line and connecting to each other,
• the ring-shaped body includes an inner peripheral surface of the ring-shaped body located inside in a radial direction with respect to the center line and an outer peripheral surface of the ring-shaped body located outside in the radial direction,
• in each of the sets of basic components, the second component is adjacent to one side in the circumferential direction with respect to the first component,
• each of the first component and the second component is composed of at least filaments bonded to each other,
• each of the filaments is a filamentous member containing a resin material and magnetic powder dispersed in the resin material,
• one end and an other end of each of the filaments composing the first component are located on the outer peripheral surface,
• each of the filaments of the first component extends and spreads along the radial direction from the one end toward the inner peripheral surface, changes its direction and extends and spreads toward one way in the circumferential direction, and further changes its direction and extends and spreads along the radial direction toward the other end,
• in each of the filaments of the first component, the direction of the magnetic moment of the magnetic powder, which is the total magnetic moment of each particle of the magnetic powder at each portion along the center line of the filament, is a direction along the center line of the filament, and a magnetic pole on the one end is a first pole, and a magnetic pole on the other end is a second pole,
• one end and an other end of each of the filaments of the second component are located on the outer peripheral surface,
• each of the filaments of the second component extends and spreads along the radial direction from the one end toward the inner peripheral surface, changes its direction and extends and spreads toward one way in the circumferential direction, and further changes its direction and extends and spreads along the radial direction toward the other end, and
• in each of the filaments of the second component, a direction of magnetic moment of the magnetic powder, which is a total magnetic moment of each particle of the magnetic powder at each portion along the center line of the filament, is a direction along the center line of the filament, and a magnetic pole on the one end is a second pole and a magnetic pole on the other end is a first pole.
