PURPOSE: To provide a nonreversible circuit element, which can be made low in height and avoids short-circuiting caused by a solder ball, and communication equipment using the element. CONSTITUTION: While using a magnetic assembly 5 provided with a ferrite 54 and central conductors 51, 52 and 53 connected thereto in respectively different directions, chip capacitors C1, C2 and C3 and a chip resistor R are connected between the ports of the respective central conductors and a metal case 8 but by forming a hole closely to the terminal of a chip component to connect ports P1, P2 and P3 on the metal case 8, the generation of the solder ball is prevented and even when the solder ball is generated, short-circuiting between the terminal electrode and the metal case is prevented.
