PURPOSE:To prevent the generation of electrical damage in a connecting part, by constituting a heat generating resistive layer gripped by a pair of electrodes of an electricity-heat converter constituting a recording head in such a manner that the resistivity distribution is made higher in the central part thereof compared to the connecting parts with the electrodes. CONSTITUTION:An electricity-heat converter 2, a heat acting part 7, an orifice 5, a liquid emitting part 6 or the like are provided to the surface of a base plate 3 and a liquid of which the volume is abruptly increased by receiving the action of heat energy is emitted from the orifice 5 as liquid droplets to carry out recording. In this case, the electricity-heat converter 200 is constituted from electrodes 200-1, 200-2 and a heat generating resistive layer 202 as well as sid heat generating resistive layer 202 is formed so as to make the width in the vicinity of a central part 204 wide compared to the connecting parts 203-1, 203-2 with the electrodes of said resistive layer 202. By this structure, heat is almost generated at the central part 204 and the heat generating is low at the connecting parts 203-1, 203-2 and, therefore, electrical damage of the connecting parts 203-1, 203-2 is prevented. |
