Disclosed is an optical connection component manufacturing apparatus that manufactures an optical connection component in which a refractive index matching body is attached to a front end face of an optical fiber. A movement mechanism, an X-axis motor, and a movement stage that move the optical fiber set a first interval at which a refractive index matching liquid held on a holding face is adsorbed, by a Coulomb force according to the charging, onto a front end face of the optical fiber charged by a static electricity generating device and then enlarge the interval. The static electricity generating device applies electric charge to the optical fiber in the state of the first interval and continuously applies electric charge to the optical fiber even after the interval starts to be enlarged.
