Abstract
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(electrical length λ/4), an antenna connection conductive member(electrical length λ/4) that is a circuit board connected to the antenna, an opposite side conductive memberthat is a circuit board opposed to the antenna connection conductive member, and an electric connection portionthat electrically connects an edge portion, which is on the opposite side to the antenna, of the antenna connection conductive memberand an opposite side edge portion, which is opposed to the edge portion, of the opposite side conductive member(electrical length λ/4) are included. A gain on the opposite side to an LCD side casingbecomes large when seen from the antenna, and the electric currents are counteracted to be small and consequently a gain becomes small on the side of the LCD side casing
