An oscillating circuit includes N nodes outputting oscillating signals, a main loop circuit including N inverting circuits, and a plurality of auxiliary loop circuits. Each inverting circuit in the auxiliary loop circuits is connected in parallel with even numbers of inverting circuits cascaded in the main loop circuit. The circuits for feeding back signals from outputs to inputs of the respective inverters of the main loop circuit have circuit configurations equivalent to each other. Each inverting circuit in the main loop circuit and the auxiliary loop circuits drives an output line such that a phase of an output signal is inverted with respect to a phase of an input signal and has driving power that becomes lower when the phases of the output signal and the input signal are inverted with respect to each other than when the output signal and the input signal are in phase with each other.
