摘要： An optical connector includes: an optical fiber; a ferrule with an insertion hole that accommodates the optical fiber; a housing that accommodates the ferrule and that includes two lock holes formed therein; two springs that sandwich the optical fiber therebetween, and that bias the ferrule in a forward direction of the optical connector; and a support portion that supports the two springs from a rear direction of the optical connector. The support portion includes a first divided member that is combined with a second divided member and two latch portions locked in the two lock holes. When the insertion hole extends is the front and the rear directions, the two springs are disposed along left and right directions of the optical connector, and a vertical direction is orthogonal to the front, rear, right, and left directions, the two latch portions are disposed side by side in the vertical direction.
