A mobile phone unit is provided in which a characteristic of an antenna is improved and SAR is reduced without lowering an antenna gain during communication. An antenna 26 (electrical length lambda/4), an antenna connection conductive member 22 (electrical length lambda/4) that is a circuit board connected to the antenna 26 , an opposite side conductive member 42 that is a circuit board opposed to the antenna connection conductive member 22 , and an electric connection portion 24 that electrically connects an edge portion 222 , which is on the opposite side to the antenna 26 , of the antenna connection conductive member 22 and an opposite side edge portion 422 , which is opposed to the edge portion 222 , of the opposite side conductive member 42 (electrical length lambda/4) are included. A gain on the opposite side to an LCD side casing 4 becomes large when seen from the antenna 26 , and the electric currents are counteracted to be small and consequently a gain becomes small on the side of the LCD side casing 4.
