Claim 10:
11. The power amplifying device according to claim 7, wherein
each of the base electrode of the plurality of bipolar transistors includes three main base-electrode portions that are separate from each other and that are disposed side by side in the first direction,
each of the plurality of bipolar transistor includes the emitter mesa layers disposed between the center main base-electrode portion and the respective two outer main base-electrode portions, and
the first capacitance device connected to the center main base-electrode portion is disposed so as to be shifted in the second direction relative to the two first capacitance devices connected to the respective outer main base-electrode portions, and is disposed so as to overlap the two first capacitance devices partially in the first direction.
