Abstract:
In an optical fiber scanning apparatus, an optical fiber to which a permanent magnet is disposed and which is configured to emit illumination light from a distal end portion is arranged in a hollow portion where a magnetic field generation unit is disposed of a frame body, the frame body for which a cross section of the hollow portion is a square includes a first frame body for which planar coils are disposed respectively on a first surface and a second surface that are orthogonal to each other, and a second frame body for which planar coils are disposed respectively on a third surface and a fourth surface that are orthogonal to each other, and which is bonded with the first frame body, and the first surface to the fourth surface configure inner surfaces of the hollow portion.
