A connecting socket configured to connect a connector is provided. The connecting socket includes a conductive member, an opening, and an electronic member. The conductive member has a recess. The opening is formed on an end of the connecting socket and communicates with the recess. The electronic member is accommodated in the recess, and has a main body and a plurality of cantilever structures. Each of the cantilever structures includes a fixed end, a free end, a first contact point, and a second contact point. The fixed end is connected to the main body. The free end is disposed between the opening and the fixed end. The first contact point and the second contact point are disposed on opposite surfaces of the cantilever structure. When the connecting socket is connected to the connector, the first and second contact points respectively contact the connector and the conductive member.
