PROBLEM TO BE SOLVED: To provide a current breaking unit which can be easily mounted on a printed board. SOLUTION: The current breaking unit has a conductive spring part as a part of an electric circuit mounted on the printed board, a conductive first mounting part connected to one end side of the spring part, a conductive second mounting part connected to the other end side of the spring part, a supporting part connected to the opposite side of the spring part of the second mounting part, and a cut-off part formed at a second mounting part side of the supporting part. The first mounting part and the supporting part are inserted into a through-hole and a supporting hole of the printed board respectively. The second mounting part contacts with a wiring pattern in a state of restraining spring force of the spring part for making the second mounting part separate from the wiring pattern connected to heat radiating parts of the printed board. The cut-off part is cut off in order to cut off the supporting part from the second mounting part after soldering the first and second mounting parts. By the above, the current breaking unit can be easily mounted on the printed board. COPYRIGHT: (C)2005,JPO&NCIPI
