In the portable telephone of the present invention, a transmission power upper limit value (STEPLIM) in accordance with temperature (T) is found (S 1 , S 2 ), whether the transmission power set value (STEPn) of the next slot exceeds the upper limit (STEPLIM) or not is determined (S 3 , S 4 ), and when it does not exceed, a control signal value (Vc) in accordance with the transmission power set value (STEPn) is applied to a variable gain block ( 11, 13 ) (S 5 , S 7 ). When it exceeds the upper limit, a control signal value (Vc) in accordance with the transmission power upper limit value (STEPLIM) is applied to the variable gain block ( 11, 13 ) (S 6 , S 7 ).
