It is possible to provide a timing generation circuit which can generate a pulse rise edge and fall edge at a timing smaller than the frequency of a repetition signal generation circuit and a phase shift circuit which can be used in the timing generation circuit. The phase shift circuit which inputs a repetition circuit outputs a signal having a phase shifted by a predetermined amount according to the repetition signal. A phase shift controller controls which phase of signal from the first to the M-th phase is to be outputted by the phase shift circuit. A counting circuit counts the output signal of the phase shift circuit by a predetermined number and generates a counting end signal when the counting value has reached a preset value. Thus, the counting circuit outputs a signal of synthesis timing of the repetition signal timing and the phase shift timing shifted by the phase shift circuit.
