An OCT catheter and a method for manufacturing the OCT catheter, with which the operation time, manufacturing cost, and the risk of breakage of a spliced portion between a short-length fiber and an optical fiber contained in an interior member can be reduced, are provided. An OCT catheter 1 A includes an interior member 10 that contains an optical fiber and that is to be inserted into a body, a metal tube 20 that guides the interior member 10, and an optical connector 30. The optical connector 30 includes a ferrule assembly including a short-length fiber and a ferrule fixed to one end of the short-length fiber, and is connectable to a rotary joint of an OCT system. The other end of the short-length fiber and one end of the optical fiber contained in the interior member 10 are fusion-spliced together to form a spliced portion. The spliced portion is disposed in the metal tube 20.
