Abstract (en)

A fiber guide (31) includes a main body (50) and a fiber passage (60). The fiber passage (60) has a first surface (61) disposed mostly in a first region (A1) and a second surface (62) disposed mostly in a second region (A2). The second surface (62) is inclined to be away from the first surface (61) as approaching the outlet (55). The first surface (61) is inclined by 5 degrees or less with respect to the axis (50L), and the second surface (62) is inclined by 5 degrees or more and 30 degrees or less with respect to the axis (50L). In the outlet (55), a first portion (55-1) included in the first region (A1) is smaller than a second portion (55-2) included in the second region (A2).
