Abstract: A wiring board design support apparatus, in which a plurality of vias are arranged on a wiring board, includes a design information storage unit that stores design information of vias and wirings to be arranged on the wiring board, and a wiring board via arrangement unit that moves, on a basis of the design information, positions of lattice points arranged with same intervals in vertical and horizontal directions by a given moving amount in a vertical direction and a horizontal direction while alternately changing a moving direction in the horizontal direction of the lattice points for each row of the lattice and alternately changing a moving direction in the vertical direction of the lattice points for each column of the lattice, so as to arrange vias at positions of the lattice points after movement.

Abstract: To improve wiring housing property, with preferable work efficiency, without deviation in the vertical direction or the horizontal direction, without expanding via arrangement areas.
