PROBLEM TO BE SOLVED: To provide a backplane bus whose dimensions can be changed according to the number of printed board, which can be more miniaturized, the size of the unit case can be made variable, the space factor can be improved, and the maintainability is also improved, and to provide a unit case for an electronic apparatus using it. SOLUTION: This backplane bus includes a first connector 2, a second connector 3, a third connector 4, and a fourth connector 5, and their respective insertion directions are four orthogonal directions in the same plane. At least one of the first connector 2 and the third connector 4 is the connector for mounting the printed board 7, the second connector 3 and the fourth connector 5 have insertion directions in the opposite direction respectively, and their connector shapes are a convex shape and a concave shape which can be inserted into or removed from each other, and the other backplane bus 1 having the same configuration can be mated with them in the insertion/removal direction.
