PROBLEM TO BE SOLVED: To provide an IC socket with an electric connector capable of attaining stable electric contact as the whole electric connector terminal. SOLUTION: A spring part is formed into a zigzag-lined state where plural radius parts are piled while their round faces are directed alternately in opposite directions and is split into two spring parts in its substantial middle part, horizontal stepped parts D1, D2 with edge parts E1, E2 provided in their tips are projected in middle parts of a V-shape formed by contact end faces 16b, 16c in a contact part 13, a lower side of a soldering ball 25 is contact-supported by the stepped parts D1, D2 or the edge parts E1, E2, and energizing force applied to the contact part 13 contacting with the soldering ball 25 is made weak and contact force with respect to a cotact face of a PCB is made strong, while bordered in the middle portion of the spring part, at the time of a test. |
