It is aimed to reduce friction resistance generated in a resilient contact portion. A shield connector is provided with a dielectric for accommodating an inner conductor, a tubular outer conductor for surrounding the dielectric, a resilient contact portion formed in the outer conductor, and a cut portion formed in the outer conductor and enabling a supporting portion supporting the resilient contact portion, out of the outer conductor, to be resiliently deformed. If the resilient contact portion contacts a mating outer conductor and is resiliently deformed, the supporting portion supporting the resilient contact portion is resiliently deformed by a reaction force from the mating outer conductor. Since a resilient deformation amount of the resilient contact portion is reduced by as much as the supporting portion is resiliently deformed, friction resistance generated in the resilient contact portion is reduced.
