To provide an optical fiber connector that is excellent in heat radiation, high in a degree of freedom in design, small in manufacturing error upon manufacturing, easy in manufacturing, excellent in maintainability, and has a cooling function by a cooling medium with high quality and high durability, and durable even to a further high output transmission in the future.SOLUTION: An optical fiber connector has: a connection part that is located on a side to which an end part of an optical fiber connects; an insertion part which extends in a longitudinal direction of the optical fiber, and through which an optical fiber core wire is inserted; an introduction part that introduces a cooling medium; an ejection part that ejects the cooling medium; and a cooling medium flow channel that is formed in the interior of the connector so as to run along the insertion part. The cooling medium flow channel has a flow channel from the introduction part to the ejection part via a vicinity of the connection part integrally molded by a 3D (three-dimensional) printer.SELECTED DRAWING: Figure 1 【課題】放熱性に優れ、設計自由度が高く、製造時の製造誤差が少なく、製造し易く、メンテナンス性に優れ、高品質、高耐性で今後の更なる高出力伝送にも耐えうる冷却媒体による冷却機能を有する光ファイバ用コネクタ。【解決手段】光ファイバ用コネクタであって、光ファイバの端部が接続する側に位置する接続部と、光ファイバの長手方向に延び光ファイバの心線が挿通される挿通部と、冷却媒体を導入する導入部と、前記冷却媒体を排出する排出部と、前記挿通部に沿うようにコネクタ内部に形成された冷却媒体流路と、を有し、前記冷却媒体流路は、前記導入部から前記接続部近傍を経由して前記排出部に至るまでの流路を３Ｄプリンタにより一体的に造形した。【選択図】図1
