PURPOSE:To suppress the voltage drop of a common electrode and to make it possible to arrange a heat generator to the end part of a substrate, by wiring the common electrode or indivisual electrode arranged in an end part side to an opposite side. CONSTITUTION:Lead parts 2a constituting an indivisual electrodes 2 are parallelly provided on the surface of a substrate 4 at a predetermined intervals so as to cross the direction along which a substrate end part 4a extends and a partial glaze layer 5 as a heat accumulating layer is laminated onto the lead parts 2a along the substrate end part 4a so as to laterally cross said lead parts 2a. Rectangular heat generators 1 provided to the upper surface of the partial glaze layer 5 an indivisual part 2b is connected not only to one end part of each heat generator 1 in the side of the substrate end part 4a but also to each lead part 2a. The indivisual electrode 2 is constituted of the indivisual part 2b and the lead part 2a. Each of said lead parts 2a passes under the partial glaze layer 5 to be drawn around to the side opposite to the substrate end part 4a and wired up to a drive circuit. |
