Abstract To provide an optical fiber bundle and an optical fiber bundle device which can increase the amount of an outgoing beam.SOLUTION: In an optical fiber bundle 2 formed by bundling a plurality of optical fibers, an end part 21 at least on one side of the optical fiber bundle 2 in an axial direction is a taper part 23 formed into a tapered shape. In the end part 21 at least on the one side of the optical fiber bundle 2 in the axial direction, a portion at least on the side of an end surface 23t of the taper part 23 is a heat seal part 26 formed by heat-sealing the plurality of optical fibers. The plurality of optical fibers respectively have a numerical aperture NA of 0.4 or more.SELECTED DRAWING: Figure 1 【課題】出射光量を向上できる、光ファイババンドル及び光ファイババンドル装置を、提供する。【解決手段】光ファイババンドル2は、複数の光ファイバを束ねてなる光ファイババンドル2であって、光ファイババンドル2の少なくとも軸線方向一方側の端部21が、テーパ状をなすテーパ部23であり、光ファイババンドル2の少なくとも軸線方向一方側の端部21において、テーパ部23のうち少なくとも端面23t側の部分は、複数の光ファイバどうしが熱融着された熱融着部26であり、複数の光ファイバは、それぞれ、開口数NAが0.4以上である。【選択図】図1
