The time base error detecting circuit of a sub-carrier for simplifying a hardware includes a delayer for getting a delayed signal component, a first switch being switched by control signals, a second switch for generating a sine wave and a combining signal of the sine wave, a subtracter for generating a phase error signal of the sine component, and adder for generating a phase error signal of a cosine component, a divider for dividing output signals from the subtracter and adder and for getting a tangent component on the phase error, and a phase error detector.
