ABSTRACT:
An ink jet head comprises a discharge opening for discharging ink, an electro-thermal transducer for generating thermal energy used for discharge of the ink, and a substrate for supporting the electro-thermal transducer through a heat-accumulating layer, the electro-thermal transducer being applied a voltage to supply the thermal energy to the ink so as to generate a bubble in the ink, thereby discharging the ink by pressure upon generation of bubble, wherein the substrate is a substrate obtained by bonding a metal plate being machinable and having higher corrosion resistance than Al, onto a main metal substrate a main component of which is Al, by clad bonding.
