PROBLEM TO BE SOLVED: To maintain excellent transmission characteristics of an optical fiber array. SOLUTION: The optical fiber array 10 is provided with a substrate 30 on which storage grooves 34 for storing an optical fiber 24 are formed, a cover plate 12 which covers the optical fiber 24 stored in the storage grooves 34 and an adhesive layer 16 which joins the substrate 30 on which the optical fiber 24 is stored in the storage grooves 34 and the cover plate 12. Adhesive grooves 36 in which the adhesive layer 16 enters from the storage grooves 34 for storing the optical fiber 24 to an end part of the substrate 30 are formed on the substrate 30. The adhesive grooves 36 are formed approximately in the V shape at cross section and formed approximately in parallel with the storage grooves 34. In addition, the adhesive grooves 36 are formed near an outermost storage groove 34a (an adhesive groove 36a) and near an end part of the substrate 30 (adhesive groove 36b) among the storage groove 34. It is desirable to form at least one adhesive groove 36 from the outermost storage groove 34a to the end part of the substrate 30 and a plurality of adhesive grooves are also formed.
