An oscillator includes: oscillation units ( 11 through 1 n) outputting oscillation signals of different frequencies; a transmission line ( 15 ) to which outputs of the oscillation units ( 11, 12 ) are connected, the transmission line having a characteristic impedance corresponding to an output impedance of an output terminal (Tout); and a low-pass filter 818 ) connected between the transmission line ( 15 ) and the output terminal.
