Optical fiber bundle manufacturing apparatus, light guide, endoscope having light guide, and method of manufacturing optical fiber bundle

An optical fiber bundle manufacturing apparatus comprising:

• a winding member configured to rotate about a rotary axis to wind up an optical fiber wire;
• a guide member configured to move in a direction parallel to the rotary axis to guide the optical fiber wire to any one of:
• p first winding positions,
• a converging winding position, and
• q second winding positions,
• on an outer peripheral surface of the winding member, where p is a natural number of 2 or more and q is a natural number of 2 or more, and where p is a different number than q;
• and
• a processor configured to perform processing to move the guide member such that
• a first branching portion branching into p branches at the first winding positions,
• a converging portion converging the first branching portion branching into p branches into one at the converging winding position,
• a second branching portion branching into q branches from the converging portion converging into one at the second winding positions, and
• a connecting portion connecting the first branching portion and the second branching portion,
• are formed in this order by the optical fiber wire.
