PROBLEM TO BE SOLVED: To secure proper communication quality. SOLUTION: This radio communication terminal is constituted so as to allow the user to fold a lower casing 13 provided with a final control element 18 and an upper casing 14 via a hinge part 15; the upper casing 14 is provided with a memory stick slot 23, being inserted of a communication extension stick 24 having accommodated an antenna element 51 for extension of communication together with a storage medium 53; also the lower casing 13 or the upper casing 4 is provided with a main body antenna element 21, and the body antenna 21 in question and the memory stick slot 23 are arranged apart, whereby this terminal can prevent deterioration of antenna properties by preventing a user's hand which holds the lower casing 13 for operation from touching the antenna element 51 for expansion of communication, when the user performs radio communication with the antenna element 51 for expansion of communication, and can prevent each other's waves from interfering with each other, when the user performs radio communication, using the antenna element 51 for expansion of communication and the main body antenna element 21, thus this can secure proper communication quality.
