A two-point modulation type phase apparatus and a wireless communication apparatus capable of achieving a reduction in circuit scale and low power consumption while maintaining modulation precision. It is possible to provide a D/A converter (150) that converts the inputted digital baseband signal to an analog signal, an adder (110) that adds an output signal of a D/A converter (150) and an output of a loop filter (135) to output to a control voltage terminal of the voltage controlled oscillator (105), and a peak control section (140) provided at a front stage of the D/A converter (150) that carries out smoothing of peak portions appearing at the inputted digital baseband signal, at a two-point modulation type phase modulation apparatus (100) that modulates a-carrier frequency signal using an inputted digital baseband signal by setting a frequency dividing ratio of a frequency divider (115) of a PLL circuit based on an inputted digital baseband modulation signal, and adding a voltage corresponding to a signal that is an inputted digital baseband signal analog-converted for supply to a control voltage terminal of a voltage controlled oscillator (105).
