Abstract
A printing head comprising a plurality of printing electrodes positioned in parallel with each other on a surface of an electrically insulating board. At least the sliding surfaces of the printing electrodes, or electrically conductive projections formed near the front edge of the plurality of the printing electrodes, are coated with a high melting point metal whose volume resistivity is not greater than 10.sup.-4 .OMEGA..multidot.cm and whose melting point is not smaller than 1500.degree. C. The high melting point metal may be comprised of one or more of the elements of the group of Mo, W, Ru, Rh, Re, Ta, Ti, and Zr. The electronically insulating board may be comprised of an elastic layer.
