To provide a connecting unit capable of improving both the electrical conductivity and the resilience of a contact contacting an external connection part such as, in particular, an IC, and to provide a method for manufacturing the same.
For instance, the top face, the bottom face, and both side faces of a conductive member 40 are completely surrounded by an auxiliary resilient member 41 as shown in Fig. C. The conductive member 40 is composed of a material having specific resistance lower than that of the auxiliary resilient member 41. The auxiliary resilient member 41 is composed of a material having a yield point and an elastic modulus higher than those of the conductive member 40. Thereby, both the electrical conductivity and resilience of the spiral contact can be improved well.
