A multicore fiber (1A) includes a plurality of cores (11A, 11B) arranged in a matrix, and single cladding (21) surrounding the cores (11A, 11B). An outer shape of a cross-section perpendicular to the longitudinal direction of the cladding (21) is formed into a noncircular shape having the smallest diameter in a prescribed direction and having no recess. Two or more cores (11A, 11B) are arranged in a prescribed direction while a number of cores (11A, 11B) outnumbering the number of the cores arranged in the prescribed direction are arranged in a direction perpendicular to the prescribed direction. The multicore fiber (1A) is bent in a prescribed direction for use.
