A coupled ring oscillator includes n ring oscillators ( 20 ) each including m inverter circuits ( 10 ), and a phase-coupling loop ( 40 ) in which mxn phase-coupling circuits ( 30 ), each of which couples signal phases at two points in a certain phase mode, are connected with each other to form a loop. Connection points at which the inverter circuits ( 10 ) are connected with each other and the connection points at which the phase-coupling circuits ( 30 ) are connected with each other are connected bijectively; and each of the inverter circuits ( 10 ) is connected between two points that divide the phase-coupling circuits ( 30 ) into two parts at a certain ratio.
