A recording head is disclosed which comprises an array of pin electrodes of copper wires and a plurality of pairs of auxiliary electrodes. Two lead frames are mounted to sandwich the array of pin electrodes, with one end of each lead frame serving as auxiliary electrode regions and the other end serving as lead terminals. Standing studs are planted on a printed circuit board for common connection of electrically conductive wires which connect to the pin electrodes at their tip portions and pass through the spacing between the two adjacent lead terminals.
