The present invention relate to a socket for a nano SIM card first to third connection parts arranged in a transverse direction, and fourth to sixth connection parts arranged in parallel with the first to third connection parts. The socket comprises: first to sixth terminals each comprising a contact part configured to be brought into close contact with an associated one of the connection parts of the nano SIM card and a soldering part configured to be soldered to a print circuit board; a housing comprising through-openings for first to sixth contact parts, which are formed at positions corresponding to the positions of the respective connection parts of the nano SIM card when the nano SIM card is inserted into the socket; and a cover coupled to the housing to define a space between the housing and the cover so that the SIM card is inserted into the space.
