PROBLEM TO BE SOLVED: To provide an electric switchboard, having a bus of a large current capacity to which a conductor can be readily connected. SOLUTION: The electric switchboard houses multiple circuit breakers (1) that receive power from multiple external power supply devices on the basis of a power supply device by power supply device; relay conductors (8, 9, 10), the one ends of which are connected to the output terminals (6) of the respective circuit breakers; and buses (2, 3, 4), to which the other ends of the relay conductors are connected in common and which are extended in the horizontal direction with their width faces facing front. The buses are constituted of multiple bus bars, having the same sectional shape mutually disposed in the same perpendicular plane with gaps (G1) of predetermined dimensions in the vertical direction. Connecting conductors (8, 9, 10, 16, 17, 18) are provided which are constructed of multiple connecting bars, so disposed that their width faces face the front, and they sandwich the width faces of the individual bus bars between them in cooperative manner. Connecting screws (11, 19) are inserted in the holes formed in the connecting bars and the gaps of the predetermined dimensions between the bus bars, adjoining each another in the vertical directions, and the bus bars and the connecting conductors are connected by these connecting screws.
