Semiconductor device socket

aiteta, tb, tctdteA contact terminal comprises: a pair of movable side contact pieces (M) and (F) which pinch or release a ball-like electrode portion (DVa) of a semiconductor device (DV); a fixed side terminal (T) having on one end a contact point coming into contact with an electrode group (PBE) of a printed wiring board (PB); and a fixing portion (C) which connects proximal end portions of the pair of elastic movable side contact pieces (M) and (F) to the other end of the fixed side terminal (T). The fixed side terminal (T) formed into a curved shape is elastic and has the one end thereof joined to the fixing portion (C). The fixed side terminal (T) is formed of a plurality of curved portions (, and ) and the contact point provided continuous with one another.
