Abstract
An ink jet print head includes first terminals 22 and 22', which are located at the side ends of a cover member 2 as a vibrating plate, and are connected to discrete electrodes 6 and 6' for selectively applying signals to piezoelectric vibrators 5 and 5'. A semiconductor integrated circuit 30 includes second terminals 31 and 31' that are arrayed corresponding in position to the first terminals 22 and 22' and generates a drive signal in response to an external signal. The first terminals 22 and 22' are connected to the second terminals 31 and 31' such that a gap of H in height is formed between the semiconductor integrated circuit 30 and the piezoelectric vibrators 5 and 5'.
