The present invention relates to a pulse generation apparatus for generating a pulse signal having a pulse width controlled, and a pulse signal having a pulse width controlled with high precision is generated by a circuit suitable for conversion into LSI. The pulse generation apparatus comprises: a polyphase clock generating unit for generating polyphase clocks having different phases; a clock selecting unit for selecting one clock from among polyphase clocks on the basis of a pulse width indicating signal; a counting unit for counting clocks selected to output a pulse end signal at timing at which a counted value based on the pulse width indicating signal has been reached; a pulse output unit for starting the generation of a pulse signal on the basis of a pulse generation trigger signal to terminate the generation of the pulse signal on the basis of a pulse end signal; and a delay unit for delaying a pulse generation trigger signal by an amount of delay based on the pulse width indicating signal to thereby generate a count starting signal for instructing to start the counting of clocks in the counting unit.
