A power amplification apparatus includes, between a first amplification element for amplifying an input signal and a first output terminal, a second amplification element for further amplifying the input signal amplified in the first amplification element to output to the first output terminal, and a first switch element for controlling the second amplification element to be stop condition. Further, between the first amplification element and a second output terminal, a second switch circuit for controlling the supply of an output from the first amplification element to the second output terminal is provided. When outputting a medium power, the operation efficiency of the power amplification apparatus is improved by reducing a power consumption. Thereby, a total operation efficiency of the power amplification apparatus which outputs either the input signal amplified to a large power or the input signal amplified to a medium power by switching is improved.
