ABSTRACT:
An ink jet head producing method includes forming a first flow path forming member in a portion constituting a flow path side wall, which constitutes at least a partitioning portion between flow paths on a substrate; forming a pattern as a mold for the flow path, the pattern being formed over the substrate and a portion of the first flow path forming member; forming a second flow path forming member on the first flow path forming member and the pattern, the second flow path forming member being formed of a material corresponding to the first flow path forming member; forming the discharge port in the second flow path forming member; and forming the flow path by removing the pattern.
