Abstract
An optical fiber array includes: a multicore optical fiber in which the outer peripheral shape of cladding in a cross section has first and second convex surfaces symmetric with respect to a first axis, and first and second surfaces symmetric with respect to a second axis and closer than extensions of the first and second convex surfaces to the second axis; an arrangement component including a groove having a trapezoidal shape having first and second side surfaces mutually facing such that sectional shapes become closer toward a grove bottom, and a bottom surface; and a pressing member. With the first surface in surface contact with the pressing member, the first convex surface or a boundary portion between the first convex surface and the second surface, and the second convex surface or a boundary portion between the second surface and the second convex surface are in contact with the first and second side surfaces, respectively.
