A socket (10) includes a first insulator (20), a second insulator (30), and contacts (50). The first insulator (20) is in the form of a frame. The second insulator (30) is movable relative to the first insulator (20). The contacts (50) each include a support portion supported by the first insulator (20) and are disposed within the second insulator (30). The contacts (50) each include an elastic portion (54) and a movable portion (55). The elastic portion (54) is linked to the support portion and is located between the support portion and the second insulator (30). The movable portion (55) includes a contacting portion (55c) for contact with a connection object (60). The movable portion (55) is farther than the elastic portion (54) from a periphery of the second insulator (30) and is movable relative to the second insulator (30).
