Provided is a production method for a catheter for an optical coherence tomograph (OCT) the production method can shorten work time suppress production costs and reduce breakage of a melt fusion connection part between short optical fibers and interior body side optical fibers. Also provided is an OCT catheter. An OCT catheter (1A) is provided with an interior body (10) in which optical fibers are embedded and which is inserted into the human body a metal tube (20) which guides the interior body (10) and an optical connector (30). The optical connector (30) has a ferrule assembly that includes short optical fibers and a ferrule which is fixed to one end of the short optical fibers and the optical connector is connected to a rotary joint of the OCT. Positioned in the metal tube (20) is a melt fusion connection part formed by fusing together the other end of the short optical fibers and one end of the optical fibers embedded in the interior body (10).
