PURPOSE: To provide a printed board with a wiring arrangement separable into such a size as to permit recording by using one side of the printed board and by exposing one time.

CONSTITUTION: In a multiple needle recording head wherein conductors 1 are arranged on the surface of a head at a predetermined pitch to become a plurality of recording electrodes 1a and 1b and each of groups of a predetermined number of the conductors 1 is held in a separate bundle and is secured on base boards 4, each group of a predetermined number of the conductors 1 conductively connected by a connecting conductor 10 in a matrix form is secured separately on the base boards 4. Even if the conductors in the same group connected to the same control circuit are separated into a plurality of bundles, e.g. two bundles, and are connected to the wiring base board 4, the groups 8 of the conductors are conductively connected in a matrix form to provide conduction between each group. For this reason, there is no need for the wiring pattern to bring the conductors bundled on the right half side of the head and those bundled on the left half side thereof into one group on the wiring base board and the individual wiring patterns can be formed separately on a plurality of the half sides of the wiring base board.
