PROBLEM TO BE SOLVED: To provide a main line branch board in which tightening operation of a fastener for fastening a bus bar and a branch conductor can be carried out from the front side, installation space can be reduced, and the effect of gas on the bus is suppressed. SOLUTION: The main line branch board 1 comprises: a plurality of bus bars 10 (A-C) extending vertically; a plurality of circuit breakers 17 arranged vertically while directing the primary terminal 17a toward the bus bars 10 (A-C) side; branch conductors 23L and 23R for electrically connecting the primary terminals 17a of the circuit breakers 17, respectively, with the buses 10 (A-C); and fasteners 26 and 27 for fastening the branch conductors 23L and 23R to the bus bars 10 (A-C). The bus bars 10 (A-C) are arranged while being shifted in the front and rear direction and the right and left direction wherein the distance L2 for shifting the bus bars in the right and left direction is sufficient for tightening each fastener 26, 27 from the front side.
