The invention is a continuous finishing apparatus for a slide fastener having a slider introduction portion for successively introducing a slider by intermittently running a slide fastener chain, wherein, a slider introduction member thrusts into the space portion when the slider held by a slider holding member is brought into a space portion and set therein, moves downstream of the slide fastener chain within the space portion, holds an engaging element disposed at a downstream end portion of the space portion, and then, continues to move to the downstream for carrying the slide fastener chain, and wherein the slider is introduced and set along the same chain upon this carriage. Because the slider introduction member carries the slide fastener by holding the engaging elements on an edge of the fastener tape, which is least elongated, no disagreement occurs in position of corresponding right and left engaging elements.
