子。 An end-face focusing lens such as a gradient index lens with a quarter period length is fixed in the sleeve tube, and an insertion hole for an optical fiber connected to the lens is formed in a flange portion having a diameter larger than the inner diameter of the sleeve tube. The tip of the support tube is brought close to the end surface of the lens with a slight gap, and the flange portion is brought into contact with the end surface of the sleeve tube to adhesively fix the flange portion and the sleeve tube. An optical fiber terminal characterized in that a fiber is passed through the insertion hole of the support tube, and the fiber and the support tube are bonded together.
