Abstract
A connecting unit for establishing a connection with external connecting portions of an electronic device includes a base and a plurality of spiral contactors having a conductive layer and an auxiliary resilient layer. The top face, the bottom face, and both side faces of the conductive layer are completely surrounded by the auxiliary resilient layer. The conductive layer is composed of a material having a specific resistance lower than the specific resistance of the auxiliary resilient layer. The auxiliary resilient layer is composed of a material having a yield point and an elastic modulus higher than the yield point and the elastic modulus of the conductive layer.
