An optical fiber array having a structure where a V-groove substrate (5) in which a V-groove (6) is formed and a lid substrate (4) integral with the V-groove substrate (5) are provided, and a core section (2) of the end of the optical fiber (1) from which its cover is removed is placed on the V-groove (6) and pressed from above the V-groove substrate (5) against the V-groove (6) by means of the lid substrate (4) to secure the core section (2). A resin layer (9) is formed at least on the portion at which the lid substrate (4) is brought into contact with the core section (2) when the lid substrate (4) presses the core section (2). During the assembly of the optical fiber array, the optical fiber is hardly damaged when the lid substrate presses the core section against the V-groove and hardly breaks because of damage.
