It is an object of the invention to provide a pulse generation circuit and a modulator for realizing a high On/Off ratio in a small circuit scale and with lower power consumption. A short pulse generation circuit according to the invention includes an oscillator 101, a control signal generation circuit 102, an intermittent frequency multiplier 103, a filter 104, and an output terminal 105. The oscillator 101 and the intermittent frequency multiplier 103 are active circuits implemented as active elements. A continuous signal is output from the oscillator 101 and is input to the intermittent frequency multiplier 103 and the intermittent frequency multiplier 103 intermittently operates according to a control signal output from the control signal generation circuit 102, thereby generating a short pulse signal, and a spurious component is removed through the filter.
