Abstract
An ink jet head includes bump-shaped electrodes and of a recording element board and a drive element board, respectively. Of both electrodes, Young's modulus of a material forming the electrode is made smaller than Young's modulus forming the other bump-shaped electrode. With this construction, when the electrode and the electrode are press bonded to each other, since the electrode is relatively smaller in rigidity to the deformation, it deforms for itself thereby minimizing deformation in the electrode. As a result, when a new board is mounted, even if the electrode has an error, good bonding can be carried out.
