An object of the invention is to provide a portable radio apparatus capable of reducing a local SAR occurring when it is set close to a human head by suppressing concentration of the current flowing through an antenna element and a ground board. A portable radio apparatus according to the invention includes a first case 8 ; a second case 9 ; a plate-shaped antenna element 1 provided in the first case 8 ; a conductor ground board 2 provided in the second case 9 and having a ground potential; at least two feed points 3 spaced from each other, for energizing the antenna element 1 ; a radio circuit 5 provided on the conductor ground board 2 ; a power distributor 6 for outputting so as to distribute a high-frequency power input from the radio circuit 5 ; and a phase compensating unit 7 for compensating phases of high-frequency powers input from the power distributor in in-phase to output the compensated high-frequency powers to the at least two feed points respectively. The at least two feed points 3 supply the high-frequency powers input from the phase compensating unit 7.
