In order to that there is no region in which an ink pools, a particle made from
the ink is hardly generated, and high reliability is archived, an ink jet recording
head comprising a substrate; a resin body, which defines an ink discharge section,
formed on the substrate; and a heating resistor provided on the substrate, an ink
chamber being formed between the heating resistor and the ink discharge section,
resin parts being positioned in the resin body along the ink chamber, a material
of the resin part being the same as that of the resin body, is provided.
