Abstract
An ink jet recording apparatus includes a recording head having plural discharge openings for discharging ink, a liquid chamber for storing the ink to be supplied to the discharge openings, a liquid flow path for communicating the discharge openings with the liquid chamber, and plural energy generating elements for generating energy to be used for discharging the ink from the discharge openings. The head also includes a substrate having the energy generating elements provided thereon and a transfer molded structural member made of thermosetting resin. The structural member has a concave portion for forming a liquid flow path, and the structural member is fused to the substrate.
