A first amplification section and a second amplification section included in an amplification apparatus amplify two constant amplitude signals generated by vector decomposition. An impedance inverting circuit inverts the impedance of the signal amplified by the second amplification section. A combining circuit corrects the phases of the signal amplified by the first amplification section and the signal whose impedance is inverted by the impedance inverting circuit, and combines and outputs these signals. The combining circuit includes a line which is (lambda/4)+gamma in length and which is an asymmetrical circuit element and a line which is (lambda/4)-delta in length and which is an asymmetrical circuit element.
