Abstract: There is provided a connector which is capable of routing a flat cable in a desired arbitrary direction and at the same time preventing the flat cable from being broken. A concave portion is formed in a housing, and a convex portion is formed on a cable-holding member for being slidably fitted in the concave portion.
