Abstract
A contact includes a support member, a first spring portion, a second spring portion, a third spring portion and a fourth spring portion. The first spring portion extends obliquely upper forwardly from an upper end of the support member and has, at an apex, a first contact point which contacts with an IC package. The second spring portion is bent from the first contact point, to extend obliquely lower rearwardly and have a first touch portion. The third spring portion extends obliquely lower forwardly from a lower end of the support member and has a second contact point which contacts with a printed-wiring board, thus being in contrast with the first spring portion with respect to the support member. The fourth spring portion is bent from the second contact point, to extend obliquely upper rearwardly and has a second touch portion for contacting with the first touch portion.
