Provided is an optical connector in which an optical fiber can easily be passed through a protection member and manufacturing time can be shortened. Also provided are a photoacoustic wave emission device that uses said optical connector, and an optical connector manufacturing method. The present invention comprises: an optical fiber (10) that is provided with a ferrule part (11); a cylindrical connection member (12), one end section thereof having the ferrule part (11) fixed within the cylinder, and the other end section thereof having one end of the optical fiber (10) drawn out therefrom; and a cylindrical protection member (13) that is provided around the optical fiber (10) drawn out from the other end section, wherein the cylindrical connection member (12) has a protection member contact surface (12d) that the protection member (13) contacts, having been inserted from the other end section, and the cylindrical connection member (12) has a ferrule-side tapered surface (12e) that is formed between the protection member contact surface (12d) and the ferrule part (11), such that the inner diameter of the cylindrical connection member (12) gradually increases toward the ferrule part (11) side.L'invention concerne un connecteur optique dans lequel une fibre optique peut facilement passer à travers un élément de protection et le temps de fabrication peut être raccourci. L'invention concerne également un dispositif d'émission d'ondes photoacoustiques qui utilise ledit connecteur optique, et un procédé de fabrication de connecteur optique. La présente invention comprend : une fibre optique (10) qui est pourvue d'une partie de ferrule (11); un élément de connexion cylindrique (12), une section d'extrémité de celui-ci ayant la partie de virole (11) fixé à l'intérieur du cylindre, et l'autre section d'extrémité de celui-ci ayant une extrémité de la fibre optique (10) extraite de celle-ci; et un élément de protection cylindrique (13) qui est disposé autour de la fibre optique
