The emission energy generation element which becomes feverish in order the circuit baseplate for the liquid drop emission head, the liquid drop emission head, the liquid cartridge, is formed on the liquid drop emission

摘要

PROBLEM TO BE SOLVED: To provide a circuit board for a liquid droplet discharge head, a liquid droplet discharge head and a liquid discharge cartridge having a configuration which reduces the amount of scatter of finished dimensions so as to improve an allowable current value by splitting wide wiring and restricting a wiring width in order to enhancing reliability in the wiring itself having a possibility of breaking, in addition to a measure for a protective film.;SOLUTION: A discharge energy generating element used for discharging liquid droplets is formed as an electric energy converting element 3. In the circuit board for a liquid droplets discharge device having an electrode wiring 4 for supplying electric power to the electric energy converting element 3 by connecting the electric energy converting element 3 with a driving power source, at least one part of the electrode wiring is constituted by a wiring pattern 4a split into a plurality of sections.;COPYRIGHT: (C)2007,JPO&INPIT
