ABSTRACT:
An improved substrate for an ink jet head includes a pair of first wiring electrode layers disposed on a base member through a first electrode contact layer, and a pair of second wiring electrode layers disposed on a pair of first wiring electrode layers through a second electrode contact layer composed of an electroconductive material such that the pair of second wiring electrode layers correspond to the pair of first wiring electrode layers. Either the first electrode contact layer or the second electrode contact layer contains a heat generating resistor layer capable of being energized upon the application of a voltage through the pair of first wiring electrode layers or the pair of second wiring electrode layers.
