Abstract: An optical receptacle includes a fiber stub, a block, and a first elastic member. The fiber stub includes an optical fiber, and a ferrule provided on one end side of the optical fiber. The block is separated from the ferrule and has one end surface, an other end surface, and a through-hole extending from the one end surface to the other end surface. A portion of the optical fiber protrudes from the ferrule and is inserted into the through-hole. The first elastic member fixes the optical fiber in the through-hole. The portion of the optical fiber includes first to third portions. The second portion is provided between the first portion and the third portion. A core diameter at the first portion is smaller than a core diameter at the third portion. A core diameter at the second portion increases from the first portion toward the third portion.
