The present invention is directed to a non-reciprocal device which easily secures the same planarity in the bottom surfaces of the external terminals and the case bottom surface. The case 7 houses a circuit board 1 and a gyromagnetic component 2 , such that the lower surface of the circuit board 1 faces the internal surface 711 of the bottom portion 71 . A plurality of side walls 72 are arranged with a space 722 therebetween on the periphery of the bottom portion 71 . External-terminal forming portions 11 to 13 of the circuit board 1 each protrude from the external side surface of the body 10 and are led to the outside of the case 7 through the space 722 . The bottom surfaces of the thick portions 14 of the external-terminal forming portions 11 to 13 are formed on the same plane as the outer bottom surface 712 of the case 7 . Connection electrodes 151 to 153 for center conductors are connected to the terminal portions 311 to 331 of the center conductors 31 to 33 inside the case 7 . External terminal electrodes 156 are formed on the thick portions 14 and connected via the connection conductors 157 to the connection electrodes 151 to 153 for center conductors.
