PROBLEM TO BE SOLVED: To make separation or the like hard to occur in a holding member even under a severe environment and to maintain superior properties. SOLUTION: In an optical fiber array, the tip end of an optical fiber is stored in the holding member 2 consisting of a base plate 3, which is formed with a storing groove V-shaped in cross section (V-groove 4) for storing the optical fiber 1 on the upper face, and a cover plate 5 for covering the upper face of the base plate 3; then, the optical fiber 1 is fixed in the storing groove by filling an adhesive between the base plate 3 and the cover plate 5. In this optical fiber array, a distance Y between the base plate 3 and the cover plate 5, and a distance L between a contact point of the optical fiber 1 with the storing groove and the cover plate 5, are designed to be in such a relation as L/6<=Y<=L.
