To provide a non-conductive clamp capable of tightly fitting a cable to a metal chassis.

A cable 23 is placed on an upper surface 5a of a placement part 5, which is bent at a hinge part 4 so that the placement part 5 is almost parallel to a presser part 13, and a movable side projection 18 is engaged with a fixed side projection 10. Thus, a tip part 16a of a spring member 16 contacts the cable 23 and elastically deforms. The portion of the cable 23 which is out of the placement part 5 is pressurized with the tip part 16a under its elastic repulsive force, to pinch the cable 23 with a metal chassis 21. The cable 23, at the portion pressurized with the tip part 16a of the spring member 16, tightly contacts the metal chassis 21. Thus, noise elimination effect is improved thanks to capacitive coupling between the metal chassis 21 and the core wire of the cable 23.
