An optical fiber connector apparatus includes: an optical receptacle including a first optical fiber and an emission surface from which light transmitted by the first optical fiber is emitted; an optical plug including an incident surface upon which the light emitted from the emission surface is incident and a second optical fiber that transmits the light incident upon the incident surface; a sleeve that holds the emission surface and the incident surface, with the emission surface and the incident surface being arranged so as to be opposite to each other; a piezoelectric element provided to one of the optical receptacle and the optical plug; a spring mechanism provided to another of the optical receptacle and the optical plug; and a control section configured to control the piezoelectric element according to a light quantity of the light transmitted by the second optical fiber.
