<P>PROBLEM TO BE SOLVED: To provide an electrical apparatus which improves the durability against a surge by preventing breakage of an element constituting an electric circuit and achieves reduction in size of the element, a board and the whole. <P>SOLUTION: In a plurality of electric circuits 20, discharge gap parts 24 are provided between input terminals 21 and functional circuit parts 22. When a voltage of one electric circuit 20 of the plurality of electric circuits 20 reaches a predetermined voltage or higher by the surge, the discharge gap parts 24 promote discharge between the one electric circuit 20 and the electric circuits 20 which are adjacent to the one electric circuit 20. By discharging between the discharge gap parts 24, energy of the surge which a resistance element 26 of one electric circuit 20 should absorb is partly borne by the resistance element 26 of the adjacent electric circuit 20. Therefore, a load of the resistance element 26 of the each electric circuit 20 is reduced, and the capacity of the resistance element 26 connected to the each electric circuit 20 can be reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
