Abstract: An optical connector includes a plug frame including a ferrule insertion portion. An eight-sided regular polygonal attachment hole, into which a four-sided regular polygonal flange portion of a flange is fitted, is formed in the ferrule insertion portion so that vicinities of outer corner portions of a four-sided regular polygon of the flange portion come into contact with inner corner portions of the eight-sided regular polygonal attachment hole, thereby preventing rotation of the flange centered on an axis direction of the flange. A ferrule is inserted into the plug frame while a rotation position determined by the flange portion and the attachment hole is adjusted relative to a direction of eccentricity of an optical fiber in a ferrule cylindrical body, and the ferrule is fitted in and held by the plug frame.
