Abstract:
An ink jet print head substrate capable of precisely blowing fuse element to store data reliably is provided. An ink jet print head incorporating such a substrate and an ink jet printing apparatus are also provided. The interlayer insulating film formed over the fuse element is made of a material that has a lower melting point than the material of the fuse element and which forms a cavity therein by heat produced when the fuse elements is blown.
