<p>An optical fiber array substrate (11) has on its one surface eight V-shaped grooves (12) for fixing 8-core optical fibers (14) arranged in parallel to one another and V-shaped side groove portions (13) formed outside of the outermost V-shaped grooves (12) located in the vicinity of the both sides of the substrate (11). The outer heaps (12c, 12d) forming the outermost V-shaped groove (12) have a summit of an identical height to the summit (12a) of the inner heap and the bottom (13a) of the side groove portion (13) has a height lower than the contact point (12e) between the ridge of the V-shaped groove (12) and the optical fiber (14).</p> |
