1. 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
in each of the filaments, a direction of a magnetic moment of the magnetic powder, which is a sum of the magnetic moments of each particle of the magnetic powder at each portion, is aligned in a direction substantially along a center line of the filament, forming a predetermined angle therefrom.
