ABSTRACT:
A printer head chip includes a plurality of ink compressing chambers which include heat-generating resistors and which are disposed side by side on a substrate. The printer head chip is used to discharge ink inside the plurality of ink compressing chambers from a nozzle by driving the heat-generating resistors. The printer head chip further includes an ink flow path groove, which is formed in the substrate and which is connected to each of the ink compressing chambers, for supplying ink to each of the ink compressing chambers. The invention makes it possible to supply ink to the printer head chip without increasing the size of a printer head, and to simplify the structure of the printer head.
